Talking about analog drums priority, I’d go AR for easy predefined drums. You can go deeper with A4/AK, much more modulations with envelopes and lfos, but the sweet spots are not easy to set. It has no master distortion compressor, and AR AMP Overdrive seems to have much more balls. Easily punchier with AR imho.

A4/AK is much more versatile for analog stuff, AR envelopes / lfos are really limited, but you can get good mono synths, probably better than A4/AK for bass as said.
AR samples engine brings other territories, bit reduction, single cycle sample chain…

AR perfs are interesting for momentary tweaking, but with more than 4 perfs, it’s physically difficult to play all. With A4/AK it’s much easier to play the 10 perfs subtly or not imho, and you can mute tracks at the same time.

A4/AK can be definitely acid, but I much prefer my Xox Heart for Tb303 stuff. Perfs helps a lot for sweet spots though.
