Eneloops seem pretty hardy but I wouldn’t want to leave them in one of those dumb wall chargers. I like my Angeleyes charger (see my review). It’s not the quickest (my Soshine SC-F3 can charge an AAA eneloop in an hour @ 800mA) but it can discharge, refresh, shows capacity etc. and stops when charged.
If I was charging eight cells every day I’d simply get another Angeleyes. Best is relative to your needs and budget.
