Late posting, just saw this thread.
Welcome to abused Vera users club. I switched almost 2 years ago now and never looked back. When Vera Plus came out, it had such protentional and a loyal user base with great developers. I was running Vera Plus for I think 8 or 9 years, and had been experiencing deteriorating support from both Vera/Ezlo itself, as well as broken plugins that I constantly had to try to work around. When I switched, I had been monitoring the evolution of Ezlo, but it never seemed ready for prime time for me.
If you used Reactor on Vera, MSR is your answer. You can migrate your existing rules from Reactor on Vera to MSR easily.
Others have mentioned you can use Vera as a Z-wave radio. This is true, however, it's only capable of so much. If you want to use newer devices, Vera just can't take full advantage. I'm running my Home Assistant setup on a Rpi 4 with a Aeotec Zwave stick, and 80 Z-wave devices on the network, with hardly an issue. 75% of the devices are 700 series or newer with support for S2 encryption (won't get that on Vera Plus). I run MSR on my Fedora NAS server, and they work well together.
I'm constantly amazed at the possible integrations that I couldn't even dream about on Vera Plus.
