US Unlocked... VZW radio vs full VZW conversion for international use

I just picked up the standard Unlocked HTC 10 and I'm looking to use it as my Verizon daily driver. I'm also looking to use it overseas while I'm in Germany for a month (using whatever plan I find when I get there... recommendations would be appreciated, but I digress).

Are there any pros/cons to flashing the Verizon radios vs converting to the full Verizon version for when I make it overseas?
