AT150MLX versus the 2M Blue

I plan to purchase one or the other of these cartridges this afternoon. Yes, I know, short notice!!

Does anyone have any comments about either, or has anyone done A/Bs?

I'm replacing an AT440MLa; I have had a 150MLX (came premounted on an old table I bought used) and really enjoyed it, but it was old, dirty, etc. I did clean it.

I've never...NEVER owned an Ortofon, though I can't really say why. Before the AT440MLa I was using a Denon 110, and before that a Shelter 201. I don't want to go back to MC if I can get around it, which is why I've honed it down to the two I've mentioned above.

Thanks!
