I passed on the FX45 for the H3. The reason I liked the FX is beacause of it's unique and agressive look. The H3 wins hands down in the same category. I felt like the FX was "over-engineered" Way to many buttons gadgets and such.
I think the H3 is far more comfortable. Front and rear.
As it is, I had the entirely opposite situation my husband at the time said he preferred the FX over the H3. And we all know who won
Good luck, but if you wife is anything like me, she will buy what she wants.
