The new Jalie Stretch jeans pattern just came out and I've been wanting to sew a new pair of jeans.  I had started tracing the McCalls pattern a few weeks ago, but decided to wait on cutting them out when I heard about the new Jalie pattern.  
Here's a look at the front and back pieces of both patterns.   If you click on the picture, you'll have a better view of the differences between the two patterns.  The McCalls patterns have 1" seam allowances, but even after tracing those in, you can see a significant difference in size.  


This is before any alterations were done.   I went with the size charts and tried to trace the one that matched my measurements closest.   Jalie pattern size T matched waist and hip measurements perfectly, while McCalls size 14 pattern was within 1/2" of my waist and hip.  However,  after tracing the two patterns and laying the Jalie pattern on top the McCalls one, you can see there's a significant difference not only in style, but in sizing!  And yes, both require STRETCH DENIM.  For a minute, I thought the McCalls pattern was for non-stretch denim...  but nope, it lists both regular denim and Stretch denim, and there is a stretch meter on the side of the package.  Hmmm...
In comparison, the Jalie pattern is much more fitted from waist to knee.  The rise is a bit lower in front, and the center front slants at a slightly greater angle.  It is also much closer in angle to my favorite pair of jeans.
The CB seams on both appear to have a bigger wedge cut out than my favorite pair of jeans, though both angles are very close.
Okay. So then I compared the measurements from both patterns to my favorite pair of jeans, and because the McCalls pattern seemed way too big, I included size 10 and 12 as well... here's how they fared (Favorite jeans, area measured, Jalie, McCalls 10, McCalls 12, McCalls 14):
 7 3/4" (Front crotch:)  6 3/4" ,   7 3/4",  8 1/8",   8 1/4"
12 3/4" (Back crotch:)  12 3/4",   10 1/4",  10 1/2",  11 1/8"
37 3/4" ( Hip:)  37",  37",  38 1/2",  40"
23 1/4"  (Thigh around crotch line:)  23 1/4",   23 1/2",   24",   25 3/4"
22 1/4"  (2" below crotch line - around the saddlebag):  21 1/2",   22 1/2",   23 3/8,  24 1/2"
15"  (knee):  15 1/4",  19",  almost the same as size 10
17"  (leg opening):  20 1/4",  19 -20" for McCalls sizes
I did NOT take into consideration basic length measurements as those can easily be adjusted.   So far, Jalie seems to be closer to what I'd want to wear.
