Next vehicle for research

I know I’ve been kinda neglecting the Yak side and reason being I’ve heard that its bad(not that I wont research it) but its not on my priority list right now, but I’m trying to get a decent fighter jet maybe with some ground capabilities, I would like to know what line I should focus on.
