Is the "standard" Linn Sondek LP-12 surpassed by newer turntable brands and designs??

More than ever, the infamous Linn Sondek LP12 turntables appear for sale on Audiogon. The price of each piece varying based on the age, condition, and how many authorized factory upgrades have been done .

The question is: Is the "standard" ( without any upgrades) Linn LP-12  outperformed by newer brand turntable designs??  It seems to be getting long in the tooth as a viable high end turntable

Can someone explain what made the sound quality of this table so special and so sought after??  Is  a USED standard Linn LP-12. really worth the money??   Thanks
