However, given that all planes have a certain extent all sorts of deficiencies, yes, as a non-perked plane, the La-7 could be considered perhaps one of the, if not the, best in AH. At least - in almost every category where it directly manifests its performances edges into tactical combat advantages.
Don't listen to all those skillful pilots saying the La-7 sucks

They don't say its uber, because to them, nothing gives trouble or difficulties. However, to us average guys

, the La-7 is really a handful to fight against.
For instance, unless I can somehow feel sure that I'm very much more relativedly skilled than the other guy, I know I can't beat any La-5FN or La-7 in Fw190s, 1vs1, coalt.
Also, fighting against it in US planes, it involves clever tactics requiring lot of skill, to best it.
Fighting against it in the Bf109s, the only real chance of catching one is with the Bf109G-10, which is a really close match, with the La-7... and still it can simply disengage at will, if there is room to dive - since the La-7 dives much better than the Bf109G-10, and suffers less heavy controls due to high speed.
Basically, as an average pilot, if you see an La-7, and you're not in one yourself, it just gets really frustrating - they're almost as fast as Tempests at deck! Only about 3~5mph slower, I think.
There are a few 'versions' of different data going about the La-7, but it's a shuddering thought that AH La-7, is not even using the best of them. I don't think we can deny it's a fantastic plane under 15k range.
