People can and do write books comparing/contrasting the advantage and disadvantages of the different eyepiece designs. Again that debate often gets above my needs. In general terms, a plossl is a pretty good all around eyepiece design that when matched with appropriate QA/QC at the manufacturer level are often good work horse eyepeices...

My two cents...Clear Skies,
My experience of the plossl design is that once you get down to 10mm focal length or lower, the eye relief becomes a very small distance and you'll have your eyeball pushed very close to the eyepiece. 15mm and above are fine - I love my 20mm Televue plossl. So for these shorter focal lengths, it's worth comparing other designs, eg. the Vixen LV, the various non-plossl Televue, the Pentax and lots of others.
