TA02 and TA110 piggyback options help. RMR vs (RCR, T2, Acro etc)

Trying to complete some builds and already have a bunch of rm05’s and rm06s on my tritium/fiberoptic acogs , but started thinking for led acog models I have , maybe I’d take a different approach for a piggyback and use an RCR , Acro, or T2 .

Anyone running an alternative to an rmr on a TA02 or 110 and have thoughts? Trying to debate my next few purchases and besides costs, wondering what are the pros and cons of going against the classic acog/rmr combo.
