I am planning to purchase one of those Panther kits with interior but I am not sure which one to choose between Takom, Meng and RFM.
I would appreciate any advice regarding that matter.

Best regards

Moved from Modeling in General / Robin

Takom more of a choice:
Panther A Mid-Late Production
Panther Ausf.D 2in1 Mid/Early
Panther Ausf. D Late Production with Zimmerit
Panther Ausf. G Mid Production w/Steel Wheels
Panther G Late Production with IR & Antiair Armour
Bergepanther Ausf. A
Bergepanther Ausf. D

You can have a look at these reviews (on this site) to help you. You could also check Scalemates for specific kits and see if any reviews are posted.

RFM are the more complex kits with lots of PE. The Takom kits are more builder friendly. Most of the MENG kits don't include the engine compartment.

I built the RFM Jagdpanther, which is based of their Ausf. G kit. So the interior is 80% common. Here is a link to the build log. You can have a look at the pics to give you an idea how the RMF Ausf. G will go together.

It comes down to your capabilities. If you want to really challenge yourself, go with the RFM kit. If you want a variety to choose from, and less PE, go Takom.

David Coyne has done some excellent build articles on Track Link of such kits. Worth reading for pitfalls as he’s included some decent research about the options included too.

Based on rewievs I would go for some of Takom kits.

Do you have a link please?

Its just my opinion, but it seems a bit pointless buying a kit with a full interior if you're not going to display it visible.

Hence, I went for the RFM kit.
