There really isn't a bad jacket in the bunch. I think its a style / cost decision really. The leather has some additional protective benefits over the 100% textile jacket.
If you are not set on a leather, the REVIT Dragon
is a beautiful Jacket and its very functional. Think of it as a baby version of the REVIT Cayenne Pro
- without Superfabric, Exkin and SAS-Tec Armor - all super-high end features. So if you don't need a Dakar / Baja level of bombproofing but would like a 4-season coat which will last for a long time - its hard to beat it at $299.
Regarding the Leathers - aside from the REVIT Ignition
using slightly nicer leather and having dynax mesh on the front and back- The Scorpion XDR Shock
and the Ignition are very similar. The Ignition will perform significantly better in warm conditions when ventilation becomes a paramount issue.
A key difference is that the Mesh causes the Ignition to fall in the 3 season category, while the non-mesh upper of the Scorpion places it in the 4 season category with the Dragon.
If you want a bombproof 3-season leather with mesh - the Ignition is the winner. If Zipper vents are fine and bang for the buck is most important, the Scorpion is a high-end coat which provides great value.
As I said earlier - there is no loser here. These are all awesome coats. I have a Ducati and wear a black Ignition size 54 here in Philadelphia almost year round for my city riding.
Let me know if there is anything else I could offer.
