I've got a late 2013 15" MBP with a 2.6 GHz Intel Core i7, 16GB of ram, 512GB SSD, and a NVIDIA GeForce GT 750M, and have been using it for 5 years now it and it is a great laptop. Can run chrome, mysql server, web servers, and personal programs without breaking a sweat. The only thing it cannot run are new video games or if you are deep into ML but old games still work great (I played GTA V on it ok when that came out).
Only downside that happened is part of the trackpad stopped clicking and one of the fans starting running crazy loud. Took it in to the apple store and they diagnosed it as a swelling battery (seems like a problem for macs so if it looks like your case is fat, get it checked out). Ended up getting the battery, keyboard, trackpad, case, fans, and potentially the monitor (it looked new or was cleaned extremely well) for $300 which isn't too bad to make it feel like new. I'm probably going to keep this computer for another 5+ years unless it dies.
Would totally recommend and I would definitely not sell it for $600.
