Without decimal points, 5, 5, 6. With decimals, I am not sure, I think the latter 2 are both better as the 1st for player with higher skill, as he can use reach better without needing / worrying to cover holes (unlike me). I would choose 1st as safer / easier way to make up for my mistakes.

EDIT: After reading comments, mainly your own main_gi, I think what I wrote is answer and conflict to what is balanced. Its different for differently skilled people, its not in vacuum from other available units, and ofc playstyle / setup preference. If there's a highly frequent / popular theme / meta that could make the choice skewed / favorable for one of the units, that could be part of decision too (e.g. multiple 2-range blockers, and nr. 3 one of few unblockables).
