Very hard to compare these modern bands to MBV. If you are just looking a side by side relation, you are gonna leave disappointing.
Mainly because The genre has grown so much to a point that the sound of Shogaze diverted from its original style (there are many that copy MBV stylistically) but most modern ones include other genres in order to stay fresh and relevant (there are reason why the genre died abruptly!)
Personally speaking, I enjoy them very much, but again, I never compared them anything from the 90s. Just try out yourself and see if you like them or now, but go in fresh.
Also, on the debate of MBV and Slowdive,
Souvlaki > Loveless
but
MBV > Slowdive
