My Pelikan K200 pen with Pelikan or Jotter refill requires no more pressure to write than my M200 fountain pen. I like using this clicker pen when out of the house. It's easy to use. My Cross Century also doesn't take pressure to write. I think the "press down hard" concept is not factual. Way overblown.
Doesn't work that way for lefthanded writers, in my experience. As a lefty, you push the ball into the paper fibers, and it is tempting to use pressure to overcome that resistance. Since a fountain pen nib flows on a thin layer of liquid ink, there is much less resistance than with a metal ball covered with ink paste.
But in general, ballpoint pens are very convenient, inexpensive, and can be found everywhere. I just can't write with them really well.
