If I could somehow scrape up the extra money, do you reckon an S45 would be the better choice?
I haven't tried either so am not really in a position to offer advice but, having looked at them on the website, I would have thought that it's a question of personal preference, rather than one being "better" than the other. (On the other hand, I'm assuming there would be a difference between these two and the professional models S5 or XL (hope I've got the names right) but this would need quite a considerable extra sum of money.
Have you tried both the S40 and the S45?
My oboe teacher said that all reeds are a compromise but I think you can probably say the same thing about the oboe itself. My Marigaux, for example, is about twenty years old and doesn't have a left F because oboes didn't back then. My first oboe (a new, unbranded plastic one) did have a left F but the Marigaux is far superior in tone quality because it is a professional instrument. I decided I was putting tone as my priority and I can live without a left F. On the other hand, if I were to upgrade to a more modern instrument to have the left F, I would want a split D key (for the Eb/E trill) because the Marigaux has one and I'm used to it/like it. This would be my reason for rejecting an S40 and an S45.
My oboe teacher originally had a Marigaux, which he decided was excellent for solo playing but unsuitable for orchestral playing, which is what he does when he's not teaching. He then bought a Josef which I think is probably the most comfortable oboe I've ever tried but he had on-going problems with cracks and has replaced it by a Buffet Greenline which apparently have the reputation of being good orchestral instruments, can't crack but are very heavy.
Is there any possibility of you going to London and trying out Howarth's second-hand oboes? You might find a second-hand professional one you like at the same price as a new S40.
