It's probably a combination of what look you want, whether it's a racer or a garage queen and if you can paint it yourself (even with spray cans)
I'm going to probably do my couple of restos with spray cans, unless I buy myself a compressor, but I will also leave some items unpainted after vapour blasting for that worksy look
The bikes are only going to be racers and you can get a good result doing it yourself with patience and preparation.
