Graham, the TC drives horribly! It hardly stays on the road but it is fun and a real looker. Old ladies and little kids like it a lot since the style is probably one of the most classic British cars known generally to the public here in the States. My TD's are a big step up on the performance, comfort, and handling ladder. The TD is roomier and much easier to drive than the TC. Both the TD and TC are easy to work on and parts are very easy to obtain. We regularly take the both cars on 400 to 600 mile trips each year with our group and try to find the toughest mountain roads that we can and they are a blast. Cruising on the highways is another matter. High speeds are not relished with the engines reving so high and 60 year old crankshafts but they are great cars and a real joy to own.
There really is no easy comparison that can be made between the Morgan and T series cars. The Morgan is far and away a much more pleasant car to drive on highways aside from the suspension which is a bit rough over bumps. Mine is 20 years newer than the T cars and it naturally will be more reliable and modern. The Kent engine is bulletproof and "powerful". There seems to be a lot more flex in the chassis which sometimes is a bit unnerving. I find that the turning radius is a larger which poses some problems but that is the only handling negative I see with the Morgan.
Each marque has it own merits and downsides but as far as the thrill factor- both are equal and a pleasure to own and drive. My feeling is that the Morgan fraternity is bit more exclusive. Everyone has had an MG of some type it seems but few people have ever heard of a Morgan. Most folks I meet think that the Morgan is an MG so I have to explain the individual stories to them.
A good comparison is tough since it is really apple and oranges but in general, the above comments sort of sum it up for me. I enjoy building them and maintaining them, so as long as it has nuts and bolts and is British, I have fun with either make.
