2, iPad Pro or keep the iPad 4th generation I have?

I am thinking of getting a new iPad, as my current one is getting outdated, and I've had it since it came out. However, last year, the earphone jack became blocked, and has since been removed. So effectively, I can not use sound on my iPad 4th.

However, I am thinking of getting a new one, for the reason that I can not use earphones, and that mine will soon become slow with iOS updated.

I use my iPad everyday, but just using safari, watching YouTube and messaging.

So what should I do?

Thank you ever so much got answers in advance
