Really dumb pajama pant question

Happy New Year dear sewists!

I have a silly question regarding pajama or lounge pants.  My standard (old) pattern requires two pieces for the front, two for the rear.  Thus there are side seams and the inseams.  The new fangled patterns for my beginning sewists (4-Hers) use one pattern piece--half of the front, half of the rear--thus eliminating the need for the side seam.  Essentially one makes two tubes that stitches them together at the crotch.

Certainly the latter is easier but is there any difference in the big picture here?  We're talking pjs so fit is not a huge issue.

I am not losing sleep over this one but I am scratching my head and wondering if the four piece method has advantages.  Maybe less fabric in the layout?

Yep, fabric requirement is probably the biggest difference and also most people like the least amount seams in something they lounge and sleep in. I don't think there's a "right" or better way. It's just what you prefer.

Thanks for your response, Irene.  I was wondering about this and then had a chat with a woman I know who works in a yarn store about PJ pants patterns.  She had the same question so I figured it was worth asking.

Yes, comfort is the big reason to skip the side seam.  They also are faster to sew-up with only one seam! 

Another way to add comfort is to make your pj's inside-out.  I do this for thicker fabrics like fleece.

Or you could use a flat seam, like I do here:  http://www.johnnymangoseed.com/blogs/johnny-mango-seed-blog/6309848-pjs-for-kids
