If your budget allows then the clear winner is clearview
Charnwood though are a very good stove and cheaper. Yeoman and stovax I would say equal in quality. If your budget does not allow a clearview how about woodwarm. The hunter is not bad but I prefer villager. Villager and hunter stoves are about the lowest priced boiler stove that is a brand thats well known.
We have had three villager stoves and have found them reliable pretty economical and represent very good value for money. We had a villager AHI woodburner running 12 radiators in an old french house. It heated the radiators really well using wood only and replaced the oil guzzling boiler. If you do go for villager or hunter buy the optional flue damper.
We now have a villager berkley boiler stove heating our home here in Ireland. It was lovely and warm all over even in the very cold spell.

Have a look through and you will find the poor stoves, although not all the manufacturers are listed.
