S!
Personally I don`t think the La-5FN is the best plane.
The 109F4 will easily outturn it and climbs nearly as well, better at higher alts.
Similar for 109G2, although turn not quite as good as F4 still a little better than La5FN, and climb very close to La-5FN at low alts, better at higher.
Even the MC202 will outturn the La-5FN and can stay with it in vertical maneuvers for quite a while.
The 190A5 is not the best matchup for the La-5FN since the La-5FN does nearly everything the A5 does, plus turns and climbs a little better.
