best mobile artillery piece

as title says, which one do you think is the best (1v1) for late game support and infantry wiping duties?

Katyusha. Good enough barrage at long range to destroy support weapons and pak wall, very accurate at close range to wipe infantry. It's the best at everything.

Calliope has the best individual characteristics for shock arty, with Best in Class rocket AoE. The min range nerf did hurt it. And it still takes 2 shots to kill.

Katy only has shock arty grade barrage for the first 4 rockets, and must be terrifying close to get hits on target.

Pwerfer is good, especially stacked, doing a similar job to the Calliope.

Stuka is weird.

LM is an area denial arty, not shock arty. it takes 2 to fake shock arty, at which point it gets nasty. I've won games on endless rocket barrages.

For non-rocket arty, Priest is king. the numbers are incredible.

Katyusha is overrated as fuck.

You are reliant on a lot of luck at all ranges, you rely on the enemy to stay in your katyusha range AND on the luck previously mentioned. Your enemies move or retreat at the first volley, so you wont do much damage. However, when you spam katyushas, they will be very strong, and the bane of any axis blobber (and an OKW forward retreat point).

Calliope is okay, its basically the best allied rocket arty in the game, works good when you have one, and works better when you have 4, but i don't play USF.

The wehrmacht Pwerfer is THE most underrated rocket artillery in the game. Why? it fires all of it's rockets at once, and so a single one, used properly, can be worth several katyushas. You do have to use them at short ranges, but you can brainlessly decimate enemy infantry and support equipment. Its great when you have one, you make your enemies rage when you have more. They are fast as well, so shotgunning (point blank firing) is not even too hazardous.

Land Mattress is alright, it would be placed by most players as the worst rocket arty in the game, but even then, having rockets is better than having no rockets.

The walking stuka is good, it cuts through blobs (but not eradicating them), it can delete support equipment out of the game, and, while it can flop and kill only one model, is a very good rocket arty. a single stuka is amazing, more is probably overkill. However, sometimes a pwerfer might be better for some situations, and allies can learn to "dodge" the line of doom (or at least mitigate complete destruction).

haven't seen anyone use the priest/sexton besides myself in the recent matches. Only way of using them is to hard spam them, leveling entire areas into yellow cover is fun. Might as well use other rocket arties though, you'll earn more value out of them than the priest
