I’m currently building Meng’s Panther Ausf.A and a Takom Bergepanther Ausf.A.
Very different kits of course, since the Bergepanther have a complete detailed interior .
The Meng’s is almost finished.
I didn’t like Meng’s Tracks, I replace them with T-Rex studios tracks.
Plastic is easy to work with, some PE along the way ( nothing crazy like Aber or Voyager ) , instructions are clean and easy to follow, metal gun barrel, a lot of options for markings and good decals.
The boxart shows a Zimmerit Ausf.A but there’s no mention about any Zimm inside the box or instructions.
Takom kit, this one has quite complicated interior and suspension, but with some patience everything fits.
There’s a jig to get the suspension arms aligned and to get the tracks in shape too, that is a great tool and helps you out a lot.
But sometimes Takom has the habit of putting the sprue attachments in some difficult locations that makes cutting and cleaning a little difficult.
But I’m not that far ahead on the build to help out.

To pick one… well Meng’s kit is very , very good but I don’t like the tracks at all.
If you’re willing to get some AM tracks , Meng’s is a great choice.
I would check inbox reviews and which variants and also the instructions for both kits.
I value the tracks & suspension , this is where I spent most of the time with the build.
Also a good metal gun barrel saves time.
I hope this helps !
