Hello!
Right now i own 2 bikes and one of them is a 180 all around with mechanic brake(27.5 boost3.0 tyres)s and got a more trail one with f180/r160 with tektro aurigas comp (got them 2 yrs ago and 26 tyres) and on the mechanical on i want to upgrade to hydraulic should. And i want to sell the other bike with hydraulic brakes. Should i put the tektroa or the shimano m315 on the new bike?

If Shimano hydraulic is a choice, always choose Shimano. Even their lowest level hydraulic brakes are better than anything else.

Im getting those shimano brakes but i wondered if it wouldnt be better with those tektros because they wete kinda mid range when new

OEM Build lists are usually cost choices made by the product managers, to have a more attractive sale price as the total ..

I have personal experience with both brakes, the Tektro Auriga line and the Shimano M315 line. Both of my "daily driver" bikes have the Shimano M315s and they've both been very good. One came fitted with them from the factory, and one bike had cable discs and I upgraded to the M315s with a $45 used set off eBay. My father has three bikes (a Trek DS and two Magnum e-bikes) and all three have or had Tektro Auriga brakes. I wouldn't call the Aurigas "mid range" -- like the M315s from Shimano, the Auriga is near the bottom of Tektro's hydraulic disc brake portfolio, at least today.

He's had to replace one set of the Tektro sets due to leakage -- not with a line connection, but in two other places -- the lever piston and at the caliper. Like most (all?) hydraulic calipers, the Aurigas are "halved" -- that is, they're cast in two halves and bolted together. This joint leaked on his one set, and the brakes wouldn't hold line pressure. This was on his 2015 model Trek DS with about 1,500 miles. We probably could have tried to take it apart to see if there was a seal we could replace, but I'm not even sure it's sealed with rubber -- I think it's more likely just two machined surfaces designed to simply bolt together and not leak. Rather than mess with a $10 caliper (and the lever would still leak anyway), he just replaced the lot with a $70 used set of Shimano Deore brakes on eBay (M615).

With the kind of biking that he and I both do, we're not exploring the outside edges of performance on ANY of these brakes, but we do, of course, demand reliability. Not only did the Tektros leak (prematurely, in my opinion), but I also think the Shimanos are easier and less messy to bleed, making maintenance more enjoyable. The biggest differentiator to me is the fact that the Shimanos have a separate bleed port and bleed screw. So you connect your hose to the bleed port and then open and close the separate bleed screw to start and stop the flow. The Tektros use a single bleed screw, like automotive brakes, where the bleed screw is also the bleed port. This works fine on automotive brakes, but I think it's a little fiddly when scaled down to bicycle size.

Most of the internet seems to feel that even entry level Shimano hydraulic brakes are superior to Tektro, and my experience correlates with that. I typically look for Tektro stuff for my rim brake bikes, as I think they offer a lot of bang for the buck, but I haven't been all that pleased with their hydraulic brakes.
