To me personally, verifiability seems a vastly better criteria for inclusion in Wikipedia. It's (a) a much less subjective standard than notability, (b) well-justified by the limitations of the medium (i.e., no original research), and (c) still prevents Wikipedia from being a "dumping ground" for everything on the internet.
The only general argument for deletionism I've seen that survives is that the editor resources of Wikipedia will be stretched so thin that the checking of verifiability itself is imperiled. But (1) Wikipedia survived fine back when it had vastly fewer editors and random people were writing on a bajillion then-empty topics and (2) there are much better ways to handle this minor problem, e.g., pages are hidden from non-registered users until they reach a critical mass of contributing editors.
Measured by pure prevalence, the dominant argument seems to be about status: that non-notable items just don't deserve to be in Wikipedia. It's very hard to argue against an emotional appeal like this.
