Which is better ?

I'm looking at some unofficial concerts of Queen/Solo on both dvd & vhs right now on Ebay.

So I wanted the experts opinions on the following and which is better than which in terms of performance and Quality:

1) Roger Taylor
(LIVE IN MILAN) RARE VIDEO 1994 + XTRAS OR Live At Cyberbarn DVD ?

2) Brian May
LIVE IN BRAZIL 92 DVD OR Live at the BRIXTON ACADEMY ?

3)Queen
- LIVE AT THE RAINBOW 1974 DVD
- Live At Earl's Court 1977 DVD
- Live In Hyde Park 1976 on DVD

well Barry the current bid is $23.01 I'm struggling with this guy who also seems to be despretly wanting this item !

Thanks Barry I’m really embarrassed I don’t know what to say!!!! I think I’ll just stick the one on Ebay. Who knows me be a time will come when you’ll say where’s that Roger concert I used to have before !! so I don’t want to be responsible for that ;)
But Really THANK YOU.
