Do you need an L, no, but they are handy.
The built in meter is fine. I adjust the exposure as the camera comes up to my eye. I also can adjust the exposure and shoot from the hip. It is very light weight. Will it last as long as an M3, no, but for the price, does it need to? For me it does not. I went to Bessas as I did not want to carry my Leicas with very young kids and the potential of a mistake costing $500 to fix.
I got my first one for free with a great deal. I got a 15mm, 25mm and black L for slightly more than the average price of a 15mm several years ago. From that point I purchased a new one with a lens ($69) and traded two Kievs that even after CLA did not hold magic for me.
I agree that the T is a better choice, but these days almost twice the price. As your first camera is an R, you will need to add LTM to M adapters to work with the T. I might be changing over to a T, but my primary camera is again an M mount camera and it’s handy to have all bodies on the same mount. The L and the R feel very close to the same in your hand.
As it does not have a rangefinder built in, there is less to break if the camera gets bumped. While my L has not been dropped, it has found some very hard items from time to time and come back fine. I do not have to treat it the same as I would a camera with a rangefinder.
IMHO, the Bessa L is the perfect PS camera body for the rest of us who want control and interchangeable lenses.
