Need suggestions for a tri suit or tri bibs for 70.3?

Been using De Soto Riviera tri bib for sprints to IM since 2013 and love them

Same issues as wearing cycling bibs, which I wear 99.999% of the time.  #1 no big deal, raise top lower bibs and do it.   #2, well that takes an act of Congress and two hangers    But I've never had this issue in 10+ years of racing 

I've used these in really hot races (Silverman) and I was worried they'd be too hot (two layers and all) but it really hasn't been an issue, especially since I wore a De Soto cooling top and will again at Cozumel.  But if it does get hot, or you need access, you can always quickly take the top off, take the shoulders off and let them hang down.

What percentage of a Tri suit is look and style, how much is comfort, and how much is functionality?  

I ask because when friends got me to do a Sprtint Tri with them 7 years ago (on zero bike or swim training) I went to the sporting goods store the night before the race and bought some Speedo jammer swim trunks and an Under Armour compression shirt.  I raced in that the next morning and was better dressed than most of the people at the event.  Last year I switched from running to Triathlon and trained (even swimming and cycling this time) for a 70.3 race and did the race in the same jammer swim trunks and compression shirt as I used 7 years ago.  Again they got the job done and were better than what some people wore for the race.  I am doing my second 70.3 next month and as a self reward for all the work I am putting into preparation I made a $50 purchase and got a new Project Rudy Trisuit.  I got it because the price was right and assumed that a real trisuit would be more functional that what I had been using.  The truth is that I didn't give this purchase much more thought than I did my night before the race purchase 7 years ago.  My night before the race purchase was 90% based on look and style and 10% based on what I though might be functional.  The trisuit purchase was justified by saying it would be more functional but the truth is I didn't have a clue what would really be functional and what wouldn't be.  The trisuit does feel more comfortable than what I had been using but for all I know the Speedo Jammer Swim trunks may be more functional than project Rudy Trisuit.  

I guess the bottom line here is that when I see others asking for Trisuit recommendations and giving trisuit advise I want to know what their criterion is for Trisuits.  I have never given it much though before, but now that I have a trisuit and can compare it to what I was doing before I have a some intrest in the discussion and want to know if there is really a difference from wearing your Tri club's default two piece race kit or if by spending time to find the perfect Trisuit you can make a difference on how things go on race day.  

Tri bibs have very thin pads.  And if you really want to do it like the OG guys you'd wear a speedo

Anyway, I guess pro tour riders and pro triathletes like Mirinda and Sanders must all have bad fits   

Well...I am sure that Carfrae and Sanders are sacrificing a comfort in favor of time saving where ever they can with their respective fits.  Still their fits looks like a lazyboy sofa level of comfort compared to what some of the pioneer of the aero fit were experimenting with over three decades ago.
