The one consistent thing you'll see through all of the above recommendations is that no one is telling you to stick with the Munton's.
I'm a Notty man myself, love it, except for the fact that it always blows the top off of my ale pail. I now only use it in my 8-gallon conical, because there's enough headspace in there to keep the lid on when the Notty takes a shine to the wort. It produces a clean, crisp beer with plenty of malt profile.
I've not used a liquid yeast yet, but I will be doing so soon with a rauchbier I've got on deck. Until then, it's Nottingham for me with most everything.
