is slkr still the best gl

I would still say Kylo is the best GL to go for first if you don't have any. You get two solid teams out of his requirements, whereas the other GLs all have some junk characters you'll relic and then barely, if ever, use. He also does everything else pretty well.

As for people caught up in the "omg kenobi can beat sith raid" mania, if you care about that then Kylo is still the better option for it as his overall relic requirements are much lower.
