To my tastes, Landlord is one of those beers which doesn't bottle well. I far prefer it on draught and don't bother buying it in the bottle.
Again, to my tastes, I think most bottled beers need a little 'beefing up' compared to their draught equivalents. Many are brewed slightly stronger for the bottle (or in the case of the big breweries, diluted less) and that can help. Landlord is an exception to that rule.
As for the 'best' it really does depend on my mood, what else I've been drinking recently and so on. At the moment MrsC is getting me the various 'Revisionist' Tesco ones and they're not bad. I had some Butcombe Gold the other night which was nice. It is, fortunately, a matter of taste.
I agree that bottled Landlord isn't a patch on the cask version. It's not bottle-conditioned is why - it's had the life filtered out of it, and is then artificially carbonated. This is the reason many bottled beers are brewed stronger than their cask counterpart - to compensate for having all the character removed before bottling. Plus, like many Yorkshire beers, Landlord benefits from being drawn through a sparkler. Same goes for Black Sheep, which I love from the cask but find a bit meh in the bottle.
Not that all non-BC beers are bad, there are some decent ones out there (Oakham Inferno is one of my favourites but they've stopped stocking it in my local Tesco - boo!), but you can't expect them to be exactly the same as the cask version, and liking a cask version of a beer is no guarantee that you'll like the bottled version.
Current personal favourite from the selection on offer at Tesco is St Austell Proper Job (which
is a BC beer) - a well-balanced bitter with a good dose of hops. Fuller's Bengal Lancer is good too - a decent IPA that avoids the fashion for making IPAs ridiculously strong.
Personally, I'm not a fan of Hobgoblin - not necessarily saying it's a bad beer, it's just not to my taste. Too sweet and bland. I also can't stand the awful branding and those cringeworthy ads designed to appeal to the worst kind of real ale bore stereotype.
Some of those Tesco Revisionist beers are actually not bad at all. The Saison is a good one, though it lacks a real Saison character - whether or not this is a bad thing depends on your opinion of beers that taste of the farmyard.
