I've been using an ATX12HD RS for years.
Other friends plus our E46 M3 have used an ATX20RS, without any issue for a few years.
Still highly recommend!
The batteries last at least as long as lead acid with the low usage I put them through and the restart has saved me tons of time with how frequently I forget to trickle charge.
