There are a lot of great fly vises on the market. The two you've mentioned while maybe being comparable in price are different styles of vises. A rotary will do more but it may be more then you need/want to start. Both brands are known to have quality products.
If you do visit a fly shop they should have some vises you can try before you buy.
I sell some vises that I believe are comparable in quality and price to those you're looking at. Since no fly shop is close to you I will offer you a one week test drive on any vise I sell. Your only obligation being the return postage should you not like the product.
I am sure you will be getting many more comments on this subject. I would expect flytyer to add his experienced advice. You are beginning on a great hobby. Have fun.
How you get the line out and fishing is personal preference so as long as it works and is easy no one should care but the caster. MSB
