there's a lot of up and coming strikers at lw, and we need to see them fight ranked guys to make a better assessment.
As some have already mentioned, ridell and fiziev's kickboxing looks very crisp, aside from some defensive deficiencies. guys like haqparast and azaitar have got good power and handspeed. conor and dustin are at the top atm, we need to see how conor looks on january. gaethje is a tough, powerful dude too but i don't think that highly of him technically speaking (he def makes it work tho, he can take a punch and land a ko shot against basically anyone, and those leg kicks are $). Really exciting matchups ahead.
If i had to chose the best striker right now, i'd have to go with conor or dustin. My personal favorites: dustin and ridell.
