LOL, and then there are those of us who operate on the other end of the spectrum; I currently have three cards with a pitiful "low-5-figure credit limit", and other than maybe a Delta SkyMiles card, which because I burned AMEX in my Chapter 13 is probably unobtainium, I really have no need, want, or desire for any more cards or higher limits.
I agree that it's really subjective, and I don't think there's a one-size-fits-all answer.
Right now, I have 15 cards, and I have trouble juggling them. I keep a running log of credit card info (account numbers, expiration dates, due dates, etc., plus each month's payment info), and one section is devoted to keeping track of which card(s) to use soon or risk closure for inactivity. It's a hassle!
I totally get feeling that urge to accept/apply for a new, great card with an outstanding intro offer....but I REALLY don't want any more cards to juggle! If I had planned my cards out more intelligently, more informed, I'd only have a few and wouldn't be bothered by this annoyance every month. (I'm not closing anything, though, because I don't want to lose any history.)
I can't imagine how people with 50, 60, 80, or more cards manage them! 15 is too much bother for me, so I don't know...
@csryang I am adding the Custom Cash as my primary Restaurant/Fast Food card. But there may be months where that versatile card might be used for Travel or Home Improvement instead. In that case, I would want a decent backup for Restaurant spend....hence, the USB AltGO. It would also act as an overspill for the Custom Cash if I go over the $500 monthly cashback cap.
The AMEX BCP......where I live Walmart Marketplace codes as Grocery for me and is where we get the majority of our groceries, aside from Costco. As far as regular discount store Walmart spend, my AOD 3% is the best I have and I'm not willing to app for the Walmart MC.....just doesn't fit into my structure. (It's a Synchrony card, which is another topic entirely)
On Deck: No Plans Currently
I have 11 and an LOC. It is hard for me to keep up with these cards sometimes and they all carried a balance. I've paid all off except for 2, which I *may* have for awhile. My goal was to obtain 100k in unsecured credit, which I have, so I have no desire to obtain more. I am super impressed with y'all who can juggle all these cards. I had 3 cards closed from Comenity for inactivity LOL.
I diversify by having one card from each reputable lender. I'll try to not go over 10[currently 8], 0 annual fee/0 store cards. It's easy to manage for me using the Mint app [I check daily in case there are unauthorized charges]. I have a few subscriptions to keep them active, and use 2-4 for different spend categories. I'm a low spender btw but I like playing with them and take advantage of their 0% offers. If a new card comes out like Citi custom cash, I try to product change. Also by only having one card with each lender, I feel the limit increases are less risky than having multiple cards with HL... so far so good.
Just sharing my methods; the right amount of cards is what you feel comfortable having w/o stress and risk of losing control. I also do AZEO to keep all in order.
I hope this was useful.

Quick note, @Taurus22, the Walmart Mastercard is now issued by Capital One. 
Of course Capital One has their own quirks and I'm definitely not trying to advocate for it, but I figured I'd at least mention that it's no longer with Synchrony. (FWIW, Sam's Club is still Synchrony.)
You are 100% correct, that was a slip. Now thinking about it, I knew that....but it was instinct to still refer to Synch. I'm not really a fan of CapOne either so it's still a no-go for me.
Thanks for the correction on that....
I'm sitting on 3 cards which is already about more than I want to manage.
I have 7 credit cards. 1st credit card I got in late 2019, I did not want to try getting anymore in 2020 with everything going on. I got 6 cards this year. I think the cards I have are perfect for me. I use them every month, PIF. I don't know how people juggle more than 10 😂.
