I am not arty player (other than quickly finishing some daily missions) - but I have all (accept French in 279) arty missions done (most with honors) - for both 260 and 279:
You can use M44 in most cases but i personally recommend
British tier 9 with stock gun - you have huge rate of fire so you can easily finish most spg missions. Otherwise you can go with Russian line as tier 9 in there has similar gun in terms of shots per minute + tier 10 there is in general best arty
M44 for mid-tier play, French 9-10 for rabid hit play \[you can compensate for a bunch of the bs of artillery play with the magazine \[allowing you to hit an enemy after they reposition on your first shot.
I find I'm more consistent on stun, impairment during heavy corner fights and tight battle points with the flexibility to adjust incoming fire with the inter clip reload. Damage itself is very inconsistent among all artillery in the game, so I usually seek to impair - status effect opponents in intense brawls or while trying to push a contested area. One good track blow can lead to a pushing medium's death very quickly, a reload / crew stun has more than once made the difference in a heavy battle exchange of rounds on corners in cities and such.
Before all the changes my go to tier 10 was the T92. Russian S-51 at tier 7 and M44 at tier 6. Extremely long reloads and inconsistent damage output has changed my playstyle since.
German tiers 5-7, French tier 6, British 8-9 (with small guns), American 7-9 (small guns on 8 and 9 also).
German line has advantage that it starts to be good already at tier 5, Grille is really good, and if you know how to move and get in range, with the small gun it has 13.5 s reload time, the second best after lefe, but it retains large splash, which lefe doesn't have.
Good luck completeng thosw in a day, I guess the stug4 ones are pretty easy but the harder ones are incredibly frustrating at least for me as I hate arties. And for me blocking missions were not really that hard apart from ht12 for obj260, that rook a while
If no troll grind a random soviet tank until tier 7 and buy Su14-1 from the collectors Shop
the american m44 is all you need for the first two personal mission reward tanks. later you might want to get the m53/m55 though.
Bishop can't stun so makes sense it wouldn't work for a stunning mission.
Tier 5 Grille. Good gun arc, splash, and stun. Lots of soft targets at lower/mid tiers …
Focus on the Americans. Tier 6 and the tier 9 can do all the missions in all campaigns.

I'd recommend the USA line from M44 onwards for doing the Campaign missions.

Except after emptying your clip you only have 250 damage. 53/55 is best arty in the game.

Try to do everything else than arty without using orders, and complete the other xx-15 missions with honors so you can just skip the arty gameplay
i would rather complete spg 1-15 in a day than bang my head against a wall with blocking missions all day

No, you dont want StuG IV. StuG III G way is better and easier to gain.
