Deciphering Samsung Tablets names

[KBGXY]

I'm new to the Samsung Tablet world, trying to choose the tablet that would best meet my needs (probably a used one, due to cost)... The list of tablets in the forum shows several categories of tablet names:
Tab, Tab+letter, Tab+number, Tab+letter+number, Note...
Please tell me if there are congruent hardware features that group these? First of all, what is the main differences between the Tab and the Note?
and among the Tab categories?

Also, it would be wonderful to see a combined list, with dates of production, of all Samsung tablet-type devices? It would be really helpful, showing at a glance if a Tab A is newer than a Tab 4 or a Note 7, etc...
This would be a very useful reference !
Thank you

Some of the newer Samsung tablets:

Samsung Galaxy Tab S3 - 2017
Samsung Galaxy Tab S4 - 2018
Samsung Galaxy Tab S5e - 2019
Samsung Galaxy Tab S6 - 2019

The Note tablets are over 5 years old.

The older tablets are Tab+Number, then Tab+Letter, and Tab+Letter+Number are the newer ones.

what's your budget? if you want to go cheap the tab A is a great device. if you want to the higher end then go with the tab s6. i might save up for one.....maybe a christmas present to myself.
