Operating two hardware wallets can be manageable. I know someone who has four hardware wallets, and it's similar to having multiple smartphones. Many people choose to do this, and while it may be slightly more complicated during the initial setup, it's not particularly challenging.
Today's hardware wallets resemble smartphones, featuring a screen with a tabbing function that allows users to scroll and scan QR codes easily to send out their Bitcoin. Overall, it's not difficult to handle.
I believe both perspectives have merit; it's ultimately a choice that users need to consider. Personally, I prefer using a single hardware wallet, but that doesn’t mean I can’t operate two if necessary.
Operating them is not difficult but we will have difficulty in storing and protecting seed phrases. If you own 2 or 4 hardware wallets, that means you need to protect your 4 seed phrases and you will need more than 4 different safe places. I don't think using multiple hardware wallets and having only one place to store all the seed phrases is a wise idea.
Using more than 1 wallet to store bitcoins is not a bad idea but in my opinion, just one hardware wallet for long term storage and one hot wallet for short term storage is more than enough. Using 3 or 4 or more wallets is just wasteful and makes us more stressed because we have to spend more time protecting them instead of thinking that it will make us more secure.
