Apples or oranges?

In general, slim necks go well with shredding and larger necks (too large is sometimes a problem) make chording more comfortable. However, my Fender midsize c shape neck does just as well as my Ibanez wizard super slim neck for shredding....up to about fret 19, but the Ibanez just has a body cut for better upper fret access. Also, I personally do not like LP necks but Slash sure does. And Paul Gilbert played RG guitars but now his current Fireman has a thicker neck. Personal preference matters a lot

I think bigger necks will have better sound. I'm a sweeper so I stick to bitch sized necks haha
