I've played every samus that ever exsisted in FL basically minus rohins, so if you wouldnt mind my input...
if you were to give wes jr. 2 weeks of playing really good people to get the rust off he'd prolly take the best samus, but he's not applicable because his mom own him hardcore.... i mean SUPER HARD CORE.
esam is prolly second, but he's an annoying 14 year old that uses his age as an excuse, when it isnt one.
Phanna is prolly under that because his super tech style really throws you for a loop and you have to first think past it to even begin beating him.
Mankosuki is I think is also tied right there with phanna, he's just a generally good samus
The Eric has long since quit he probably would've been somewhere in the phanna-manko area.
Outlaw Snake would've been under wes jr. at full power >_> too bad I dont even know if he's alive.
stick rohins wherever he belongs, i dunno.
Thing is that there are actually quite a few samus's, even though i named some people that have quit. But I honestly think all of them are around the same skill. It's close enough where a good day could change the results.
