you dont have to rush feilong, you can keep him away, just hit him a few times and then lame it out…thats the hard part, to actually get the life lead. I think its 5-5. Here’s my list, I added comments for each char
Rufus vs ____
Abel-6/4 (Only because he doesnt have a clear answer to rufus rushdown and he needs to keep him out…and Abel sucks at that)
Adon-5/5 (Both characters have safe pressure, so it becomes a matter of who hits more and gets hit less)
Akuma- 5/5 (Rufus has U2, big damage and divekick, akuma has the keepaway and the vortex)
Balrog-5/5 (Rufus needs to bait him, but has enough life to take risks, boxer can keep him out, but 1 wrong guess and its pressure time)
Blanka-6/4 (U2 shuts down blanka, EX messiah kills some of his gimmicks, divekick can beat Electricity on wakeup if well placed)
Cammy-5.5/4.5 (Rufus has more life and hits hard)
Chun li- 6/4 (Chun cant get him off once he gets in)
Cody- 5.5/4.5 (cody has good normals, great AA, decent zoning and frame traps, but he has a hard time dealing with rufus’ pressure)
C. Viper-6/4 (U2 kills her…hard, rufus does big dmg, his divekick kills pretty much everything viper has on wakeup, OS U2 in your divekicks to make it more deadly)
Dan-7/3 (its dan…seriously…but I can say his DP is “ok”, but unlike the rest of the shotos, he cant keep rufus out)
Dee jay-5.5/4.5 (U2 works well vs him though not necesarily better than U1, hard time vs divekick pressure, DJ can keep him out, but he’s not guile)
Dhalsim-6/4 (rufus needs 1 opening, and then it pretty much GG, U2 shuts him down)
Dudley-6/4 (He cant deal with rufus divekick on wakeup and cant jump on rufus)
Honda-5/5 (Honda can keep him out and does big damage, rufus divekick kills his wakeup options, Honda cant hurt rufus if he places his divekicks correctly, he can only use his options to escape, and rufus has to chase him again)
Fuerte-6/4 (U2 kills his mixup, Rufus does big damage, fuerte can be annoying, but with U2 it becomes way easier)
Fei Long-5/5 (Fei has much better groung game and footsies, rufus has to play keepaway if he gets a good life lead, Fei has U2 which counters divekick)
Gen-6/4 (Big damage from rufus, his divekick owns Gen)
Gouken-5.5/4.5 (Counters are annoying, but baitable, U2 works better than U1 here IMO)
Guile-4.5/5.5 (I dont think its THAT bad to be 4/6, once rufus gets in guile has to fear his barrage of crossups, mixups and tick throws, he cant hit rufus with flashkick if he Divekicks at the correct ranges)
Guy-6/4 (U2 again…prevents his elbow nonsense, EX snake strike also does the job)
Hakan-7/3 (He cant keep rufus out, his SPD range is crap unless oiled)
Ibuki-6/4 (U2 kills her vortex and almost all her moves, she cant runaway effectively if rufus has U2)
Juri-6/4 (Juri can zone and run, rufus needs to take risks to get in, but once he’s in…he’s IN, she has low life, rufus has tons of life and does big damage)
Ken-5/5 (both characters have good rushdown and mixup, Rufus divekick kills ken’s DP on wakeup if he hits him in the shoulders, ken has awesome footsies and a mad good kara-throw, ken is also better at rushdown than ryu, but worse at keepaway, which is why this matchup is 5-5, because Rufus will get in)
Makoto-6/4 (She’s just too weak IMO, she has good normals and frame traps, her far MP is boss, but once rufus gets in its over)
M. Bison-4.5/5.5 (Bison has a slight adv here, because of his normals, pressure and run away. U2 again saves the day for Rufus, once rufus gets in its hard for Bipson to do anything, Rufus divekick beats EX PC when perfectly placed)
Rose-6/4 (This is like dhalsim, but not as bad for rose. She can apply pressure and zone, her mixup isnt great, when rufus gets in then it becomes hell for rose, also Rufus’ U2 kills her fireballs and careless Rose’s U2 pressure)
Rufus- Even…duh
Ryu-5/5 (Rufus has a hard time getting in, he needs to bait…hard. Ryu can keep him out and rush him down. If rufus can bait DPs then its even, if not, is 6/4 for Ryu.)
Sagat-4/6 (His zoning is too good, tiger knee kills divekicks, rufus has to be mad patient in this one. Rufus divekick gives sagat a hard time on wakeup)
Sakura-6/4 (She cant keep him out forever, he will eventually get in, and it will be as bad as it is for Makoto, she also has low life, her mixup can get killed by EX messiah)
Seth-5/5 (Both chars have good tools, seth can run, rush, zone and just be gay. Rufus needs only 2 combos to stun him, also U2 restricts Seth game a lot, Seth’s mixup is really good)
T.Hawk-5/5 (Rufus has to play keepaway here, the only reason this is 5/5 is because Hawk doesnt have EX green hand and his footsies are crap)
Vega-6/4 (good normals for vega, great tick throw game, but cant deal with rufus pressure at all)
Zangief 4/6 (zangief has awesome footsies, he’s got EX green hand which rapes any normal rufus can use vs him, if he knocks Rufus down it becomes really hard for rufus. Rufus has decent AAs,as well as good life, if he can play solid and keep away, he can win)
