First off, what a cool present!
I've just recently got into replica watches, and in the last couple months I've purchased a Seamaster GMT with the Asian 21J, a 45mm Planet Ocean with the Asian 21J and finally a Ultimate Planet Ocean with the ETA movement.
Cosmetically the Seamaster GMT is a great watch, hefty and solid, but the movement in mine went screwy after about three weeks.
The Planet Ocean with the Asian movement has been running perfectly accurate for me, but the fit and finish leave a little to be desired. Mine isn't the "UPO Lite" and isn't quite as accurate compared to the UPO. It's still a great watch, especially for what I paid for it.
The UPO is my newest and it is a great watch. As soon as I took it out of the box I knew exactly where the extra cost went. Hefty, solid, and very impressive. Great looking and feeling and a very classy watch.
All in all, I think you get what you pay for in either watch, it comes down to what you're really wanting to spend.
