Un-answerable question brother. You never know how a given rifle will perform until you shoot it.
If it was me, I would sell one of the SGL's and buy two new AK's, keep the other SGL for the collection.
I had an SGL like 12-13 years ago, a guy offered me 4 times what I paid for it. I sold it and bought two new AK's and still pocketed some cash, I don't regret it a bit.
