These are bifacial panels, so efficiency per square foot is also going to be way higher than anything you'll find that's even a few years old, let alone as old as these used panels you're peddling.
These panels are on average 10% more efficient than single sided new panels of similar class. Add the loss from your used panel and that's a 20% improvement for the same amount of space required at slightly less weight.
If you have acres to mess around with, by all means, get used panels.
If you're not looking to mess around or have space/weight constraints, do not leave performance on the table.
Edit: The person's comment above makes a good point, that if space is a premium buying used panels might not be best for you, since they've lost 10-20% of their capacity. However, bifacial doesn't help that much, maybe 10% more power, which at that point just buy a normal panel with 10% more capacity for almost certainly more than 10% cheaper.

You also have to factor in the lifespan of a used panel over buying new. And that's where it becomes a hobby that most people don't have time for.

As for lifespan most panels are good for around 25 years on average, but can go as long as 30 years. ( Panels from commercial resellers could have little to no use because of out of the box defects at commercial install sites, or taken down from commercial buildings after ownership changes.)
When it comes to cost, there is no way a used is not a good deal you save HUGE (as mentioned around 80% sometimes) and even after all the tax credit blah blah your still saving on average 50% but yeah you might have to replace the panel in 10 years boohoo... Thats only if space is really a premium and you want to replace with higher efficiency at that point.
Dude your not winning the new vs used battle in this one because of how cheap these panels are sold and can be purchased in large quantities. Only reason you need new is if your not DIY because most solar installer like to sell a whole system so they wont work with used or panels purchased somewhere else for warranty reasons of their install.
