Strange question, but it warrants an answer. Pierce is my choice. He had a tough ride into that part, with Remington Steele nixing it when he was at his 'Bond-prime'. Plus his wife's sad death and his inevitable family problems (can't be easy bringing up a kid as a single parent in Hollywood -i struggle as it is in S. London with a wife to help (read that as 'Does almost everything').
When his chance comes around it's fortuitous that it was a time when they'd had to pep things up quite a bit with a new director etc, but then to have increasingly poor script and mismatched directors thrown at him thereafter, well my heart goes out to the guy (lets not get carried away, though, he did get to be James bloody Bond FFS )
I'm very happy for him that he got at least one of the best Bond movies under his belt (GE) and has been vindicated since as a good actor with, not least The Matador and that tells me that he could've risen his game accordingly had the scripts been better.
Brossa, i salute you
