I have both of these sabers and I love them both!
If you are going to buy them both at some point then I would buy the Guardian now while it is on the flash sale ,as it will save you money.
If you have to pick one of them that makes it much more difficult to choose. Then it becomes more personal preference for sure and what you intend on doing with it, dueling, cosplay, etc.
I have the canon setups on mine as well. I have an ultra-edge (white looking) mid-grade blade on my Consular and a standard mid-grade (silver looking) blade on my Guardian.
If you have one type already than I would get the other to see which one you like better.
Both of these sabers have excellent craftsmanship and will serve you well. So I vote for both.
Good luck on your choice. MTFBWY!
