I've lease a 2014 and currently have a 2017 Mercedes B-Class ED (B250e). Basically, I owned the first and the last ones. Unlike the RAV4 EV, there were numerous differences over the years.
I don't know what's important to you, but the RAV4 EV beats the Mercedes in EVERY metric that matters to me:
RANGE: RAV4 EV easily wins. With approximately 40kWh available when new, the RAV4 could go 125+ miles when new. Certainly, 100 miles is doable, even as the fleet batteries degrade to 30-35kWh available.
The Mercedes is lucky to hit 90 miles when new, and last night, after a "full charge", I drove about 73 miles with about 11 remaining on the GOM. Like the RAV4, the Mercedes has "normal" charge" and "full or extended charge" settings. But, the Mercedes only has 28kWh and 31.5kWh respectively available on those settings.
POWER: RAV4 EV wins, easily.
INTERIOR VOLUME: easy win for RAV4
CONFUSING BUTTONS Mercedes is a BIG winner
Certainly, I'd rather drive the Mercedes over a Nissan LEAF or a Chevy Bolt.
We now offer JdeMO fast charging for the Mercedes, like we do for the RAV4 EV.
