I use the 14 way deluxe cart bag and love the organizational benefits. Always easy to find the right club and makes me very aware that all the clubs are in the bag before we leave a green and head to the next tee box. Plenty of pockets for storage. I also have a stand bag for when I play a course that does not allow carts. Luckily for me, the only one that falls in that category is East Lake, and I don't mind not having that full size bag that day...and neither does the caddy.

Not worried about grips wearing from the dividers as we should be changing our grips out at least once a year.

Definitely 14, my Stay Dry Cart Bag is the best. If I was still carrying, probably a stand bag with 5 or 6 dividers.

I have them all. I have just about every imaginable configuration produced, from 1, 3, 5, 6 up to 15 with the putter specific slot. My biggest peeve is not having a putter slot. Damaging a putter grip or doing the putter tug and dance for 18 holes is just annoying. I take my vintage clubs out with the 1 (more of a Sunday bag) and 3’s and carry/walk the course. Those are vintage bags too. Yes, I have more than one 3. The two smaller ones have minimal pockets (2 and 3) which keeps things to an absolute needs level. The larger bags are for drive cart only. Those are for those high-end non-caddie courses. They are just shy of staff bag size and volume. I noticed at the caddie courses that they prefer the lightweight bags with minimal slots, especially if they’re carrying more than one bag. I’ll generally travel with the midsize carry bag for both weight and room considerations. I use the light 6 or mid weight 14 slots for my push cart to minimize chatter and for ease of club removal and replacement. There’s a reason we all carry 14 clubs, and play golf on I8 different holes on 1000s of courses, and have more than one pair of golf shoes, that same logic goes into why I have so many bags, variety, options, and insanity. I love this game.

As someone who plays as inexpensive as possible. I am gonna say which ever is cheaper.

14 way divider is really good for a cart bag, but I understand while some ppl prefer less than 14, so it's great to have both options available. I prefer less than 14 when carrying my bag, because I may not have a full complement of clubs (esp. In winter) and helps keeps the bag lighter.
Even then 5 or 6 is an ideal number of dividers in order to keep wedges separate from mid irons, long irons, any rescue, driver and putter.
It then allows for using the same bag when getting closer to the summer season and more clubs in the bag. Good balance of weight Vs convenience.

Took a while to get accustomed to the 14 openings, but now that I have a system I like it a lot. Wear and tear on the grips is certainly less than with the carry bag.

I'd even go for something in middle. the irons are what typically gets hung up when sharing a slot. So maybe having a few more slots for irons with no more than 2 per slot would be a fair compromise between size and function

I like the fact that 14 slots keeps all my clubs in the correct order. Neat Freak!

never owned a cart bag personally, but looking at the likes for people that favor fewer rather than more seems that less is the preference.
