They're very different feelings, of choice vibrating, though if he's using it whilst having sex it may speed up things which may not be what you're after?
vibrating ones are so good but wouldn’t mind giving jiggle balls a try too. Guess they’d be hard to compare as are totally different sensations... maybe vibrators are better for solo play and the jiggle is good in couples play?!
The plug will be mostly for solo play, sorry I didn't mention it in the OP.
Since you all suggest vibrations, I think I'll go for that. He loved the jiggle plug so much that I can't wait to see his reaction to a vibrating one! 
As others have said it’s two different sensations, some don’t really get much from the jiggle kind but it depends on what your doing with them. I know from past experience that the jiggle plugs during vaginal penetration are a deep and gentle sensation and enhance things but from a male perspective I prefer the vibrating and curved plugs. They give more of a deep and intense feeling which really pushes on the Male G spot. The butt tingler is next level: https://www.lovehoney.co.uk/product.cfm?p=28501 Really deep and does pack an intense tingle!
I have the fun factory one. I must admit...I kind of render it pointless...but each to their own. My Mrs got it on holiday and it's been kept at mine.
My 2p on the fun factory one is, it holds smells, the material actually stink of weeks after use, no matter how hard you clean it. Also there is little gaps between the materials on the ball part, which hold traces of poo in them, I found cleaning them was a pain.
Both myself and my lady have tried vibrating toys, but neither of us get turned on. On the other hand she loves having a jiggle ball plug in her bum while we have we have vaginal sex.
Oooooo as someone who has never tried a plug that vibrates that does look worth a go, I’m all for ‘intense tingles’!
This is a wonderful toy, but dammit my enormous butt cheeks kept on switching the damn thing off whenever I moved. This was very frustrating. Tried the fifty shades jiggle plug, and I must say was very impressed with it, worn it most of the day, out and about, with a big smile on my face!
