This is a lot more simple than many people make it, and this applies to all gear. If your current bipod works for your needs, you are good to go. Now there's a couple huge pitfalls to that statement.
1) If you've never tried other gear, it's hard to know if something else works better and why/when for your use. Different bipod options do offer advantages over a harris, leg angle options, feet options, etc. Sometimes it's as simple as seeing someone use gear in a way you never thought of. With good gear like an Atlas if you don't like it, you can recoup most of your $ on the for sale forum. Use case matters, a $600k Lambo SVJ is 2s a lap faster than a $300k Porsche GT2 RS, but if all you want to do is 0-60 and 1/4 mile runs, a Tesla Plaid for $130 is faster than either. Also remember there's no shortage of sponsored guys on various forums saying how amazing their sponsor's gear is, even if it's not.
2) Slipping into the mindset that gear will fix your shooting, and justifying it with #1 above. One of my coaches used to say "Every new widget makes you shoot great for a week" and he was right. You change something, your in a positive mindset, you focus on your fundamentals more because it's new kit, and you see improvement.....until you fall back into being comfortable again. The vast majority of even even good shooters do not apply enough science to their shooting/gear to evaluate changes properly in gear or form.
3) Getting caught up in the "Buy once, cry once" stuff. Look I'm not saying that more expensive gear doesn't perform better, and I HATE counterfeit shit. However, precision rifle is getting to be more of a social status parade than trap shooting, and that's saying something. It's why we now have $1000 bipods, $700 scope mounts, $300 muzzle brakes, $300 shooting bag plates, etc. 10 years ago guys thought an Atlas was expensive, now we have bipods costing 4x as much. It's hard to blame companies when people keep paying it, and doing so only drives prices higher across the industry. I mean Sig probably gets up in the morning saying "We sell a pair of descent optic rangefinding binoculars that range to 2k, runs AB lite, connects to Kestrel/phone for weather info, and calculates your ballistics on the fly for $1000, if guys are forking out $1k for a bipod we are selling our optics WAY too cheap!"
