What's your favorite finish ?

Finishes are my latest concern and don't want to get into spray finishes if I can avoid it.  The back and sides will be walnut with a Port Orford cedar top and rich lite fretboard.   Possibly a base sealer of shellac with something over it for durability.   

I plan to test on scraps to see if I want to use clear or garnet shellac for color. 

Your thoughts on finishes?
