My AA S410 is .22 caliber and MRD is .177, so its not direct comparing, but anyway its just a personal experience and opinion.
My AA is not too pellet sensitive, it shoot well most of the pellets, but it does prefer heavier pellets and shoot JSB 16-18gn and Kodiak/Barracudas slightly better on the full power (940-950 fps).
My MRD is currently tuned specifically for competition (under 20FPE) and shoot crosman premiers 10.5gn at 895-910FPS. All Crosman/Benjamin heavy pellets (domed, hollow-points, ultra magnum) shoot almost equally well. Kodiak/Barracudas with similar weight shoot about the same as Crosman/Benjamin.
Both rifles do OK with light pellets, but at longer distance heavier pellets a little bit better.
I didn't have problems with either guns, cleaning, trigger adjustment for both and power tuning for MRD is all it took.
I also have Avanty Valiant XS40 (AA S200, CZ T200) airgun and it shoots extremely accurate with most cheap pellets including Crosman pointed 7.9gn. Tuned to 12 FPE and with extra removable cylinder it may be better choice for FT then both above-mentioned guns. Current price on those is also not prohibitive and small cylinder filled easy with the hand pump. Its a little too light to shoot of hand, but for FT with all the addons hanging from it its about perfect.
