MFSL worth it?

In my collection of LPs, from the 80s, I have a dozen or so MFSL LPs, everything from orchestral classics to Neil Diamond's "Hot August Night" to Pink Floyd's "Dark Side of the Moon". Since I bought them for their good sound and not for their future collector's value, I played them a great deal over the years and still do and they still sound very good.
 
I'd say, unless you're in a pinch for money, keep the sealed album sealed and hold on to it for a while, buy the unsealed album, take good care of it, but play it and enjoy the great sound...JMO.....Jim

My experience with MFSL goes back to the late 70's and thru the early 90's with their vinyl pressings including the original UHQR stuff.
I enjoyed the quiet surfaces and flat discs compared to commercial pressings but sometimes their EQ differed from the original...sometimes too bright sometimes just right. 
When they started producing CD's, I stopped buying them except for a few examples because they didn't sound "right".  They tweak the EQ to make the sound "better" with increased detail but most of the time I don't like the sound as good as the original pressing on vinyl.  Also, a lot of their choices in the Rock department are good Artists with lousy recordings in the first place so the MFSL treatment just makes the warts more apparent.

I'll buy their recordings if I know they sound better than a original or a remastering of an original which never seems to sound better IMHO.

Crime Of The Century is still the best MFSL I’ve heard. 
Sticky Fingers the worst.

IMO, it is of concern that you are asking others for your determining opinion? I go with my ears/gut.
