I have had numerous good guns, and have had at least three that cost as much as a new car.
The best Combo I have shot to date is the 32"/34" fixed stock Browning Unsingle Combo. It fits like a glove, hits like a freight train, and kicks like a small bore. It shoots where I look, and the perfectly regulated O/U barrel shoots high enough (6" high, or around 70/30) for ATA Dubs, flat enough for Skeet. The Unsingle can be set where I want it, which for me is almost 15" high (95+%).
It is NOT ammo or primer sensitive. It is very tunable with added weights and recoil reducers, more for desired balance than recoil reduction. Better chokes and springs are available for it. At under $4000, it may be the best deal on the market today.
As a former Browning repair center employee, I can perform whatever service it may need, parts are very available for it, and I LIKE IT.
