Doing a parallel, David released, I believe, 5 solo albums instead of Mark that released 10 solo albums not counting his soundtracks + NHB.
2 of 5 DG's albums he barely performed live. His first one is much more a experiment, and the About Face album kind of filled a gap during the Pink Floyd's dispute by Roger/David.
David never played those material after 1985 (with only one exception)
Mark was/is a active musician that released, in average, an album/tour on every 2 years (I know, there are exceptions).
Post 2006 David's releases are way better than Mark's. Every album was followed by a live DVD ("On An Island" tour have 2 DVDs) plus easter eggs, interviews and a lot of interesting stuff.
However, note that the gap between DG's releases: 2006, 2015, 2024 (1978 and 1984 doesn't count). So, every tour was an EVENT. Every tour was a celebration and every "albun/tour" was prepared to have a LOT of material.
When Mark started his solo career, after a 4 years gap, he released a epk, VHS and a CD.
During the release of STP, there was a great documentary about MK (never released officially) + the album.
I cannot affirm if Ed was THE guy with an eye (aka inteligence) for it because, since PC start to manage him, only standard material was released.
What I am trying to tell is that, IF Mark had very few solo albums, maybe his released could be more "Gilmorized".
In my opinion, I prefer more albums than live records.
However, MK solo releases could be better.
