The owners of the Semovar I know say it is great. Nice build and a sharp look with excellent performance is the general feel I get from them for the most part. QC issues do exist, however. Durability and warranty concerns also persist.
Only time will tell if they can match the legendary service reputation of Provape.
Tapped out
Disclaimer: I don't have a Provari to compare (others with both state the quality is comparible)
What warranty concerns? It has the same 1 year warranty as a Provari.
As for repair concerns, it is modular so each piece can be separately replaced. I can't say for VapeRev in the states but Cloud 9 say they will replace the chip for you. I have also seen them say the chip is pretty much plug and play and can easily be replaced by a confident user.
Having said that, it is a very solid steel construction and would need some serious trauma to damage the shell.
