Want to convert my 3x MTB to 1x for simplicity and aesthetic reasons.

Some assumption/context first:
> Primarily ride on dry paved trail / gravel / fire roads (mostly flat). No single track or downhill.
> My current 3x set-up provides a sufficient gear range.
> I have a flexible budget.

Using BikeCalc.com - Bicycle Gear Ratio Chart, my current/proposed gear set-up are as follows:

3x (22-32-44T crank | 11/32T cassette) Gear ratio range = 0.70 - 4.00
1x (44T crank with 11/50T cassette) Gear ratio range = 0.90 - 4.00

I would be setting us the 1x using the "shark" by OneUp Components - The mountain bike drivetrain specialists.

Does this set-up and math work out and -- most importantly -- will there really be much of a real-world difference between the .70 and .90 granny gear?
