I wouldn't go for Robinsons regular bitter by choice but Unicorn's OK if properly kept - I like Old Tom too, but in small quantities! I used to like Newcastle Brown but stopped drinking it after I woke up after a heavy night with my liver rather than my head aching, and as for tastes being shaped by what you grew up with, I'll always have a fondness for Old Peculier, Camerons Strongarm, and Black Sheep Special. Landlord's another old favourite (likewise Ram Tam which you seldom see outside of West Yorkshire) but I got a bit spoiled living near Keighley and drinking it in the Boltmakers!
Titanic Plum Porter is nice in bottles and fantastic on draught, and for something really special there are a couple of superb oatmeal stouts to track down, Thornbridge McConnell and North Riding Oatmeal, or for something brewed just down the road from where I used to live in West Yorks, Naylors Rum Baa Baa. The one really bad thing about lockdown and not going into Sheffield to work as far as I'm concerned is being unable to call in at the Beer Exchange in the market and get bottles of the latter two...
