On one hand you have the opinion of someone who had the bike for 6 hours, is totally irresponsible with fuel and maintenance and usually makes it perfectly clear they'd rather have been given a Ducati to test.
On the other you have owners groups who invest their own money and give opinions based on years of actual use. With the possible exceptions of some very weird single marque clubs they tend to be more honest, no fear regarding advertising revenue.
The grammar or presentation may be better (although not in the case idiots like Stuart Fillingham who combines all the worst features of both), but I'm much more interested in content.
If you want a laugh, there is a MCN review of the BMW R1100GS from about 1994. Apparently, too big for MX, an average tourer and unlikely to ever catch on
