I used to have Tamiya connectors on all my stuff, as that’s what everything came with, but after having a few issues, and having new batteries that had Deans on them I changed everything over to Dean’s.
I bought about 40 pairs of connectors and spent an afternoon swapping them over. Well worth it…although they can grub up a bit and need some abrasive cleaning. Probably depends on the quality of manufacture.
XT60s are fantastic but quite expensive.
