To be fair the 4 bumps the devices up out of the awkward "somewhat better than an Arduino, but still kinda crappy at almost everything" the 2 and 3 were stuck in. Much better I/O speeds, h265 and 4k, enough memory (and dual-monitor support!) to run a real desktop workstation on it. I skipped the 3 because two of my three Rpi2s were gathering dust after the novelty wore off and they proved to be too weak to repurpose for much of anything useful (one hangs on as an MPD server) but the 4 is way, way more capable.
