What's the best performing yet simplest way to connect to my home network while away from home?

Currently I have a Pi3+ with PiVPN on it that uses OpenVPN. I connect from my phone or my laptop and they operate basicallyeasybib  like being on the home WiFi. But I wonder if there is a better way? I also have an always on Windows 10 machine in my network.

I'm wondering mainly if there's something simpler? And faster? I rarely change phone or laptop so forget how it's setup and have to re-google what I did every time I add a device. It also feels a bit clunky generating certificates and getting them off fedloan  the Pi, and I'm sure it's also s irs.gov low, but that's probably because it's a Pi3.

Any suggestions?
