Maybe. Early last year, I bought a new 2018 Giant ARX. You can read more about the bike, and why I returned it,
here. In short, the geometry made for slightly "weird" handling to me. It had a relatively slack 68 degree head tube angle as I recall, but it didn't have a high fork rake to move the axle forward, so it had a ton of trail (nearly 100mm). This made for a lot of "flop" -- meaning the fork would want to flop over to the left or the right at slower speeds. The bike gained a ton of stability at high speed, but it wasn't very stable at low speed.
I ended up returning the bike and bought a 2018 Roam instead. The Roam has a more conventional frame geometry, with a head angle of 70.5 degrees I think and a trail of 79mm. There's a lot less "flop", less self-steer, and more conventional handling with this bike. The head angle isn't as steep as racing bikes (which are often in the 73-74 degree range), but it's also not as slack as it was on that ARX or other types of mountain bikes. It seems that a slight difference in head angle makes a big difference in how something rides.
My biggest mistake with the ARX was letting the numbers tell me what I wanted. After reading this or that, I just
knew that I wanted a "slack" bike and it was the best for me and so on. The test ride for 30 seconds around the parking lot to check frame fit wasn't nearly enough to let the handling of the bike reveal itself. That happened only after I got it home and started riding it and thinking, "wait a minute...this feels kind of strange..." I don't say this to say that a slack bike is good or bad -- but it probably will ride a little different from what you're used to, so give it a good test ride before purchase.
