Well, Skype was a good Messenger before the Microsoft buy?: Yes, Skype was not better than AIM, Yahoo! Messenger or MSN Messenger, but was a functional Messenger
Skype is a good Messenger now?: No, because Skype now is not even functional, is slow, crashes, and if you bought a NASA PC for run Skype (that even in that NASA PC will run slow) Skype will be really boring, without any good function.
The real question here is
WHY THE ACTUAL MESSENGERS ARE CREATED TO BE BORING, SLOW AND BAD? Discord is fun, but, in some old PCs will be slow, and his app don’t runs in XP, and Facebook Messenger, and entire Facebook, without a “good” connection of Internet, will run slooow.
