Pelican makes some great cases for all sorts of things. The biggest drawback is they have a great reputation and have a price that leverages that reputation to get a premium. Great for them, not so great for those of us who are budget conscious.
I don’t know anything about SKB cases so can’t comment on them.
Personally if you don’t mind paying what Pelican charges you should be happy with one of their cases. I’ve lugged tons of expensive equipment for work in their cases and never had an issue. Otherwise, do some homework and check reviews as there are other options. SKB May or may not be one.
I can tell you Plano is hit or miss. I’ve had tackleboxes by them that were great but didn’t like one of their pistol cases that I had and wound up breaking.
