Just how good are the Rosemary Co brushes? Are they actually good enough to be considered as a replacement for W&N?
Opinions on this will vary but judging from the comments here and on other sites the majority view is that they're at least as good, as long as they satisfy personal taste in brushes.
Some people prefer softer, others more spring, longer hairs, fuller belly and so on, and the Rosemary & Co. brushes are softer. Excellent overview of them
here on Handprint; the site also contains reviews of almost all quality brushes of this type.
I'm tempted to order some, but as I live stateside shipping is going to cost too much to just order one or two brushes to try out.
They're available from the CMON shop as well as other online suppliers in the US.
If you buy in person Series 7 brushes could still be considered a major contender for Best Brush In Class, because you can weed out duds (or more accurately, pick the best, since some aren't duds, just not stellar). But by buying in person you can't take advantage of the savings from online supplers (40-60% off ain't peanuts) and while if you get a dud you can return them it's a hassle etc.
But there are numerous brushes available online in the US that are more than competitive with Series 7s in terms of quality, and especially in price and consistency. Some were already named in this thread but there are others mentioned in older threads.
