My bike used to have a cheap pair of shimanos and I changed them to a pair of magura mt trail sport brakes. The new brakes feel a lil spongy and I’m just a lil worried if they aren’t sitting right (like the pads not optimally touching the rotor). My old brakes lowkey felt a lil better and stiffer. Should I bleed them? Or should I get a new rotor? 1st pic new 2nd old.

Pretty sure Magura rotors are thicker than Shimano, generally if you have Shimano brakes = Shimano rotors. Sram brakes = sram rotors
Yes on Magura (just built a XC with them front and rear).
Do not know about the Shimano but like the other guy said – there should not be any gaps.
You can’t use those rotors with metallic/sintered pads as they’re the cheap resin-only ones and will wear out very fast.

4 pistons are a lot more sensitive to pad/piston alignment than 2 pot. It looks like your caliper is misaligned in this photo. This can make the brake feel spongy.
Also 4 pistons are generally not as solid feeling as 2 pistons (does depend on the brand, ie my hopes feel very spongy compared to mt200 shimano but has loads more power and control) but it should still have a lot more braking power than the old brakes.
I hope you enjoy your squeaky fronts break because my mates magura are soooo noisy on his trials bike
