The details
-
What separates them
For thick hair, plate length and heat matter most. All 3 have 1" plates, but the BaBylissPRO's are 5" long, so each pass covers more hair. It also reaches 450°F.
The ghd and CHI both run at one fixed temperature. That's simple and gentler, but thick or coarse hair may take extra passes.
-
What buyers complain about
On Ulta, BaBylissPRO's most common complaint tags are snagging (57) and "not effective" (46). Some long-time owners say the plate coating chipped, and it has no auto shut-off.
CHI's most common Ulta tag is limited settings, with 116 mentions. Others say it snags at the corners or stopped working over time.
ghd's main drawback is price. TechRadar also notes that ghd mostly compares the Chronos to its own older irons.
-
Cost per use
At 4 uses a week, the BaBylissPRO works out cheapest per use, because its 4-year warranty covers twice as long as the CHI's 2 years. ghd doesn't state a US warranty length on the retailer pages I checked.
So which is yours?
BaBylissPRO Nano Titanium 1" Ultra-Thin Straightener
Pick it if you want: thick or coarse hair that needs high heat and fine control.
Skip it if you want an iron that turns itself off. This one doesn't.
ghd Chronos Styler 1" Flat Iron
Pick it if you want: anyone who wants one fixed, moderate temperature.
Skip it if you have very coarse hair that only goes straight at higher heat.
CHI Original 1" Ceramic Hairstyling Iron
Pick it if you want: a simple, proven budget iron.
Skip it if you want to turn the heat down for fine sections or up for coarse ones.
My pick
BaBylissPRO Nano Titanium 1" Ultra-Thin Straightener
Extended 5" titanium plates and 50 heat settings up to 450°F cover more hair per pass, and you can still dial the heat down.

Good options that didn't make the top three.

Questions
Are longer plates better for thick hair?
They help. A 5" plate covers more of each section per pass than a standard plate, so long, thick hair needs fewer passes.
Do I need 450°F for thick hair?
Not always. Start lower and only go up if hair won't stay straight. Always use a heat protectant.
Which makes the best gift?
The ghd Chronos if they like a premium brand. The BaBylissPRO if they have thick hair.
