(Unfortunately a german text).
Comparable info is available on the english wiki though:

Now...Sorry I have to disagree here. The early 109G models have been indeed slighlty less maneuverable, but still had a better engine and higher ammo capacity so could load more ammo for dogfight whilst the flight capabilities were decreased only marginally.
Basically the flight capacity therefore was identical but the armament was higher.
From Wiki: "The G series, or "Gustav", was introduced in mid-1942. Its initial variants (G-1 through G-4) differed only in minor details from the Bf 109F, most notably in the more powerful 1475 PS (1,455 HP) DB 605 engine."
Mostly because of the better engines used in G the later G models also were even faster, more maneuverable and could fly to higher altitudes (and performed better in higher altitudes than the F models)
Compare Speed:
Bf109 F-4: 670 km/h in 6300 m altitude
Bf109 G-6: 650 km/h in 6600 m altitude
Bf109 G-10: 685 km/h in 7400 m altitude
Also highest possible altitude:
Bf109 F-4: 11.600 m altitude
Bf109 G-6: 12.000 m altitude
Bf109 G-10: 12.500m altitude
Compare armament:
F-4: 2x7.92mm, ammo 500 rounds (each), 1x20mm 200 rounds
G-6 and G-10: 2x13mm, ammo 300 rounds each, 1x20mm 200 rounds
Additionally Optional armament possibilites for G ("fighter-bomber role"):
2x20mm mounted below wings
2x30mm mounted below wings
2xrocket mounts below wings
4x50 kg bomb mount below wings
1x500kg bomb mount below wings
btw. F-4 was already the heaviest armed of the F-variants, others had either even smaller calibers or less ammo onboard
So just from that I would say the G was an overall improvement on the F. There should be Tacbomber and Fighter version of this craft. To simulate the optional equipment possibilities which also heavily impacted on flight capabilities.
But without the additional bomber equipment the G-Types were to be considered equal or better than F-Types. Probably the reason why more G than F had been built I'd say ?
Therefore:
In terms of stats, Gustav should have more Air Attack, maybe Soft Attack as well, but less Air Defense and maybe Initiative.
So, IMO higher AA (+2 or even +4 compared to F), Initiative same for fighter role but lower for TacBomber role, AD same.
Me-410 in some subvariants had very heavy AA armament, and was used in a heavy fighter role (against allied bombers).
"Some modifications" of Fw-190 included also increased armor. When you add to it the weight of torpedo (Fw-190F could act as a torpedo bomber), I am not sure if it is "clearly a mistake" that Me-410 may be better at fighter tasks.
I guess Me-410 can have higher Anti Air and SA stats, Fw-190F can have higher NA and Air Defense stats.
I know that ME-410 was used as a "bomber killer" because of its heavy guns. And a torpedo was much heavier than the usual TacBomber load for a FW190F. Anyway I think even a heavy armed FW190F would outmaneuver and outfly a ME410 because of the basic machine specs. Therefore the much lower AA is somewhat irritating. Perhaps give the FW190F 10 intitiave then and the ME410 a higher AD instead of the FW190F.
I agree that the naval attack of the FW190F should be higher, maybe a +1 for that stat.
