The sine-sweep is usually the one to trust.
Ivo Mateljan, the crator of ARTA, has made some study of this subject, published here:

😀 I checked the graph in a hurry, but it was clear which one is which.
Basic mls has poor signal to noise ratio at low frequencies because it has white spectrum. Log sweep has bass boost of 10dB/decade so SNR is better at bass. Mls can use pre-emphasis to increase low frequency SNR, but I don't know if your sofware has it or not.

ok.... Thanks Svien and Elias,
So the conclusion is sweep is better with S/N at lower frequencies.
am I right ?
