Aims vs signature solar charger

[JJJJ]

I am considering adding an additional charger that can be a workhorse in charging battery packs and then feeding all parallel batteries through a bus bar to create the same Soc for all packs.

Each has already gone through top balancing and capacity testing.

Both the Aims and Signature Solar have received very good reviews. Any thoughts?

Thank you in advance

Also, did you see this DIY Solar Forum thread yet?
