I learned to fly initially on a Bulldog, and subsequently began again some years later on a PA28. The Warrior was a fat lazy dollop with a stupid and undignified entry/exit compared to the Bulldog, which had lovely crisp handling allowing for really accurate flying, and a bubble canopy for a fabulous view (which is one of the major pleasures of flying anyway).
If money isn't an issue (and £5 ph isn't exactly a fortune), go for the much better handling and more enjoyable aircraft. I don't think you'll ever regret it.
