I replaced a Garmin Edge 510 with an Elemnt Bolt. I like it a lot, but based on other similar threads, it depends on how you really use your bike GPS.
I like not having a touchscreen. I like making adjustments with my phone. I like how it perfectly syncs with Training Peaks. I like how it flashes at me when I'm doing intervals and I'm not quite hitting my numbers which keeps me conscious of my cadence. I like how seamless the software upgrades are. I like that it works the way it is supposed to without any issues every time. And hey, it's the most aerodynamic GPS unit currently out there...
