A little more information may help. Your question is a bit like asking I want a new car what should I buy? Someone may suggest a sports car, someone else a landrover.
What do you want from your boiler? how many radiators? how many bathrooms, showers? where do you want to locate it, do you want the cheapest to run, cheapest to buy, easiest to install? are you looking for the quietest possible, do you want any special features?..... you get the idea. Even then it's a subjective question, ask 10 drivers which small family car is the best and you may get 10 different answers. Much of it's down to personal choice really.
