If you'd only ever had cider made from Golden Delicious or some equally bland dessert apple, then you'd probably conclude that cider wasn't terribly interesting - but make cider from a characterful dessert apple like Discovery or from proper cider apples, and it would seem a lot better.
I suspect that's what we're seeing here. I'm no expert on cider or perry, but I do enjoy (proper, British commercial) perry when I have it - in fact I tend to have it in preference to cider if I have the choice. But obviously it's a big bet if you're planting trees without having had any good examples.
+1 to the idea of blending, for cider/perry or juice, but there's no need if you have proper perry varieties.
Here's a list of pears from a British cider/perry producer which may give some pointers :

FWIW the three perry varieties in stock at the
shop at our National Fruit Collection are
Blakeney Red,
Hendre Huffcap and
Judge Amphlett (although they can graft anything from the 550 pears in their collection if you give them time) so that might give you an idea of varieties to start with as a beginner - they all seem to be listed as heavy-cropping and lowish tannin.
Grafting multiple varieties of fruit tree onto one rootstock is a great idea for smaller spaces, particularly for things like plums which otherwise give you a week of more than you know what to do with.
I don't know if you can get her over there, but I'll put in a shout for
Beth as a dessert pear. She's small and not a keeper, but is delicious and ripens 4-6 weeks ahead of the main crop - particularly handy for climates like the UK where we're a bit marginal for classic pears like Williams.
