Hahnemuhle Photo Rag Baryta vs Photo Rag Pearl

So, I've finally narrowed my inkjet papers down to two choices, and I can't decide between them!

Basically, I sell most of my landscape photos as metal prints on aluminium, but also want to make an inkjet paper option available.

The properties I am after are:
-Wide gamut, capable of highly-saturated colours
- Deep blacks
- High-gloss (although I will probably have most of these prints laminated with glossy laminate to help achieve a mirror-like gloss)
- Physically durable surface
- Chemically durable with the right inks
- Able to be mounted onto Dibond panel without a border

The way I see it, the Photo Rag Baryta and Photo Rag Pearl are fairly similar, with the following key differences:

- Photo Rag Pearl is slightly sharper, with an arguably slightly wider gamut
- Photo Rag Pearl is less glossy (does this matter if I'm applying a high-gloss laminate anyway?)
- Photo Rag Pearl is smoother
- Photo Rag Baryta has a lighter white point
- Photo Rag Baryta is glossier
- They're both roughly as physically and chemically durable as each other

Any opinions on these papers, one way or the other?

I just bought a pack of 8.5 x 11 Baryta for $36.31 from my distributor and made my first B&W print and I'm impressed.
I'm a printing noob though and only have knowledge with the Canon Photo Glossy II and Pro Luster papers.
