I think they are all different bikes. IMO the Giant seems like it will best meet your needs being that it's the tires size you want. Yes 27.5plus are close in diameter, but not everyone likes the bigger volume. I\
If you are coming from a 3x7 you'll find the range from the 1X setups pretty close if not more on the low end (big rear cog). For bikes where I'm constantly spinning, like road and gravel, I prefer a larger choice of gearing to match my cadence, but for mtb it's not as important. Also another big win for the Giant is that if comes with a stock dropper post. It may seem unnecessary at the moment, but it's one of the "great" additions to mtbing in the past 10 years. If you really care to know why, I'll be more than happy to share. Good luck shopping and great to see your intentions to support your LBS, they need us and we need them.
