Any others with Land?

Piper for roasting (I'm biased as we grow about 250 tonnes of them)
Maris Bard for boiling; If put in to boiling water on the day of digging, you will never ever taste a better spud.
Day 2 onwards and you may as well not bother and never bother with them for chips if you are deep frying.

So, how can I see the differences from them?

Come to the uk  :)
Different climate means different spuds

I prefer King Edwards for roasting. Par' boil first, then roast in goose fat.
Yummy !!
