Is this site reliable for y-DNA???

[Jingle Bell]

I tested a counsin of mine in Cladefinder to discover my ancestor y-DNA, in CladeFinder the most likely was R-L52 or R-L51. But, i also tested in that brazilian company called MundoDNA (its free) and they gave me R-L151, which is just a sub-clade of the L52, so seens a very good analysis.
After this, i tried to compare my dad. In Cladefinder the most was E-L515 or E-L514 (E1b1a branchs), but in MundoDNA they gave me E-BY169463??? (which is actually a E1b1b branch from the E-V13).

How can be this diferent?? When i tried myself the same thing happened, in which one i should trust? They are like 50.000 years apart lol
This is the site:

If anyone who knows, for sure, your own haplogroup could test mundoDNA to see if the results they gives is actually the same i would be very grateful.

So MundoDNA gives you basically the same assignments, but more detailed.

I think it can be trusted.

Thats the problem, for two counsins of mine it worked (one was R-L52 in Cladefinder and R-L151 in mundoDNA, the other was E-M81 im Cladefinder and E-PF2546 in mundoDNA), but in Clade im E-L515 (a branch of E-M2, subsaharian E1b1a), while in mundoDNA i got E-BY169463 (a clade of E-V13, west eurasian E1b1b), in this case, one is not ancestor to other, they are like 50.000 years apart. For a reference, R and Q are apart by around 25.000 years, so its a big big error of mundoDNA or Cladefinder, bcs of that idk if im E-V13 or E-M2.
