I have to agree with Rita, that a lot of it is to do with personal taste (even prejudice!),
but I'm also deeply suspicious of Chionodoxa forbesii/lucilliae.
Last year I saw it turn up in a local park and you could tell the garden it had come from.
I use various spring bulbs before the large bulk of the perennials appear and bloom.
Crocuses are still my favourite spring bulb.
Also like the bulb irises.
Colour preferences are interesting, even with crocuses.
