Why are there more N type than P type MOSFETs?

I was looking at different transistors, especially MOSFETS and I saw that N type MOSFETs seem to be way more popular to be used in circuit design. Is there a reason for that, or am I mistaken?

One reason could be that N type MOSFET can switch loads that are in Drain, meaning that whatever the load voltage, you can turn it on/off directly with any microcontroller, provided that the MOSFET is 5V or 3.3V logic level. You could invert it and do the same with P-Channel, but N-Channel just feels more natural, since it shares common ground. Furthermore, going into design details, N-Channel MOSFETS have faster switching due to higher electron-hole mobility. Due to this, P-Channel MOSFETS have a higher resistance when fully on.

Presumably these characteristics lead to N-Channel being more common.

Wow! what a support to Kranulis! I would like to have enjoyed the same support when I was brutally downvoted, without any reason (and without comment). Curiously Andy, you were not here, and even more curiously, Olin, you were much more reserved in defending me. I'm jealous, really. Also, as you can see, Kranulis has not tried to discuss with me, nor to understand my point, and of course, not updated his answer. After all, why doing so when you enjoy such a support, and the two mandarins of this site are defending you so virulently. My bottom line: the answer has not been updated, and I will not remove the downvote. Sorry.

Andy aka‭ The joke is that a grown man (woman?) is throwing tantrums because you and Olin did not support his critique, immediately taking stabs at whoever he can identify. We literally just discussed the potential downfalls of public downvotes. This guy knows I have disagreed with him in the past and is just out for blood. Some people put their ego higher than objectivity, and that just is the reality of how humans can be. You did not support his crusade, therefore, you are now the mandarin of the site. Lovely, isn't it?

Andy aka‭ Alright, here you go: https://electrical.codidact.com/comments/thread/2919#comment-9698 https://electrical.codidact.com/posts/281322/281323#answer-281323

If you read through these, you will see how this guy handles critique. Once disagreed with, he starts stabbing in all directions, same as here. The narcissism is just unmatched: If my answer does not satisfy you, then clearly something is wrong with you or your question!

Notice also that I was not mean about it or anything, I said 'Sorry, doesn't work for me' which apparently set off some kind of a trigger.

It seems a rather lame discussion to some of those on SE. I mean, recently one guy kept having a go at me and we both got banned for 5 days. Another more recent SE discussion got me banned for a week despite the idiot totally trying to misrepresent what I said in his answer i.e. his answer was all about picking (incorrect) holes in my answer. Not sure if he got banned but I know who he is.
