I personally like Guitar Techniques. Mostly because they have the CD with backing tracks included. Not that every issue is a 5 star hit but there is usually at least one tune that interests me. Article wise I would say it about the same as all others. This mag originates out of the UK though and is not cheap. I think they run about $17.00 or $18.00 in Canada. I buy mine in the States usually because I am over there all the time. I believe the big bookstores over here carry it.
The sister mag to that one is Total Guitar which offers the same type thing.
For someone that is learning I think they are great becasue you get at least 3 full songs per issue with complete backing tracks. When you think about it, thats a good price. Also, if you have already mastered a few tunes and want a backing track you can download them at their website as well. Ther are hundreds and hundreads of them. Some are free others may cost a few bucks. But for learning purposes you can't beat it.
