yes x6 must be good. the exception would be if V turned to somehow be better which idk yet. or if x6 has some exceptions like x1 had. x1 ran better on some days but had days that were sometimes two or three-fold Forward Error corrections. i associate that with timeouts and stuff like that. it implies less stability in general.
only testing can know and it's still a personal result. i didn't really have a problem with x1 it's just that it performed slightly worse overall. [for non-vectoring lines like mine, that is]. i don't like x1 at all...
my dad also uses the internet so ill ask him and also see how games perform. i don't have anything new to add as i already know more or less how the SNR graphs will look and what error counts i would get. it's just that i didn't test to see what error counts V has during this time of external interferences. if only they were completely gone.
edit: x1 also had better bitswap, but sometimes sync'd with some bad bitswap and got stuck like that. that's why i need to re-sync x6 after 2 weeks and run it for another week. i think bitswap doesn't have a deeper meaning like SNR graphs. it's just what it is, unlike SNR graphs that can actually indicate whether or not there's something wrong with the modem code.
edit2: truth is, only long term experience of usage really counts in the end. not the error counts, SNR or bitswap graphs since those are ultimately meaningless. any modem code will always have ups, downs, and variations between different people.
edit3: i won't use dslstats again because it force restarts my 1312-b10a after a while, but johnson's stat graphs look a bit different than dslstats' graphs. that's why i can't just say "V's graphs looked better" even though i have old graphs.
edit4: any idea why dslstats did that to my device? the crash appeared to be random. did it ever crash your device? i prefer how dslstats graphs looked. more detailed and accurate than stats-server.
edit5: i'll use DSLStats before i restart the device since it has better graphs. that way i won't risk a crash. i also speed tested x6 and i can't imagine it working better. well i'm talking/thinking too much too soon
edit6: ISP is capped at 60mbit downstream. [i'll eventually call to update the package to 100mbit for free, maybe even next week. my line has 95mbit almost all the time. generic microfilters, no ferrites, generic 2(?) meter DSL cable. i used to have a better line with 110mbit but it was stolen... ISP gives 3mbit upstream for everyone]. if i connected the modem to the master socket i'd have no errors and 100mbit. but how can i pass cat6 through the walls of the house? stuck with using powerline adapters. i know, they emit unhealthy electromagnetic radiation.
