Well let me tell you a story about a man named Jed... wrong story 
I was/am fortunate to have time on my hands, which enable me to extrapolate information from a variety of subjects. Having surfed the various subs and forums, especially the DIY sub, it seems to me the liquid used will indeed affect performance, in more ways than one.
Vaporologist asked that question some time ago wrt switching to entirely VG based liquids, if I noticed that atties/cartos clogged up sooner? Yes they do.
Now many folks choose to dismiss this claim, but having been on both side of the fence, I am now in a position to say it does affect the lifespan of our equipment.
In the beginning I couldn't understand why folks were going through atties like they were going through underwear. Some were indeed using their equipment outside of their design norms and hence reporting failures. Nonetheless, I couldn't grasp how these folks were seeing short lived attys when I was seeing longevity in months compared to weeks. I knew I wasn't doing anything special so there had to be a common denominator, vegetable glycerin.
Although I roll my own and can tailor the viscosity of my liquids similar to the viscosity of PG liquids, the longevity and performance of my atties and cartos have seen a significant decrease in their lifespan. The latter is exacerbated with "sweet" juices or liquids that contain "sugars". Not so predominant with tobacco flavoured liquids (with the exception of Levy's RY4) but even tobacco flavours over a period of time affect atties and cartos.
I would have to say that although a little pre-mature with my observations that my equipment's life expectancy has been reduced by 35-50% since switching over to all VG liquids. That is a significant decrease.
Some DIYrs have claimed that using PGA vs distilled water increases performance without adding flavour. Perhaps in small quantities, but IMO PGA does change the flavour not to mention making the TH harsh (even in small amounts). The good side of this observation, in the future as I reduce nic content, I will be able to get a decent TH without the nic. Some have claimed that using PGA in their mixes cleans the atties while vaping. I have yet to observe such a phenomenon.
In closing, I have no choice in the liquid I vape any more, I have developed a sensitivity towards PG and can only use VG liquids. In my reviews (latest) I have attested to this as it will affect the reviewing criteria and findings. Although some folks enjoy plumes of vapour, there is indeed a price to pay for clouds of vapour. My recommendations to folks that are still capable of vaping PG, because many vendors now offer ratios, get yourself liquids that have a maximum content of 20% VG. Many liquids do indeed come 80/20 these days. For the longest time this is also an adopted recommendation in the DIY section, as a ratio that provided the best performance both visual, sensation, taste and provides adequate equipment longevity. I hope this is helpful

but YMMV.
