Ive long been a fan of the Anglo Arab in modern Sport Horse stallions (and mares too!)
A stallion I stood years ago - the Polish bred “Winner” - was Anglo Arab through both his sire and dam lines

He competed and won up to the GP and Nations Cup levels in Europe and North America and a huge percentage of his offspring end up in the GP ring winning as well. And in North America, winning in the Eq and Hunter rings at the biggest shows …
Redwine is another - Anglo Arab through the damline and it really seems to solidify that very typey head and build he seems to throw …

The Royal Beach Farao stallion is another. GP and World Cup winning stallion in Europe, Canada and the USA under multiple riders over a show career that spanned almost 2 decades and then a consistent winner in the Hunter Derbies and Adult Eq classes in his later years … Anglo Arab through his damline …

They all seem to descend from the Shagya Arabian - a purpose bred Anglo Arabian usually originating from the Eastern European regions. When I did my exhaustive research on Winner in the beginning (he came to me with no papers, no pedigree information, no show record - nothing. Just the information that he had apparently jumped in the “Big Ring” in Europe at one time, and was imported to Canada by the Elders and was the featured horse in the movie “Big Spender”). In the literally hundreds if not thousands of hours I spent finding out who he was and what he had done and what he had sired, I came across an incredible amount of upper level horses that shared the Anglo Arabian connection. In the jumper, eventing and dressage disciplines in Europe, and in the Hunter and Jumper rings in North America
When you look at stallions like Winner and Royal Beach Farao that competed successfully and soundly into their late teens / early twenties, you HAVE to recognize the influence the Arabian has on that soundness and show record. As a breed, as a whole, they are well known for the incredible toughness and their longevity. For them to live well into their late twenties or early thirties is the norm - its not the exception
Other than Winner having melanoma issues (he was grey) his legs were as clean as could be and he was incredibly sound as well. Royal Beach Farao is the same. There is not a single mark on any leg anywhere and I cant even begin to fathom how many huge jumps he has jumped in his career …
As a whole, these stallions and the offspring of these stallions seem to be incredibly versatile and “user friendly” I got so many pictures from owners of Winner offspring that would show them this weekend at the biggest show and winning a Championship in the hunter or jumper ring and then next weekend they slapped a Western saddle on them and went on a cattle drive and finished off by swimming with the other horses in the lake
. And with Farao, jumping around a course with a leather strap around his neck only - bridleless … 
I think for so long, because of the PERCEIVED image of Arabs being these “little crazy horses that you cant give away for free” they steered away from them in droves. Its only when you really look into the pedigrees of the purpose bred horses with Arabian blood in them, you really see and appreciate the strong contribution they offer
In closing, many years ago I bought this Anglo Arabian yearling from the late Les Ehrlick - a good family friend and horse dealer. He matured to about 15.2 but you’d never know he was “size compromised” at all … He won with a very young Markus Fuchs at the Junior International and I then sent him to the late and incredibly great Gord Kirton and his daughter Kim rode him in the Junior Jumper ring to Championship after Championship and he was then sold to Mario Deslaurier as his first Open horse. There was nothing faster in the ring in the Speed classes and Mario won class after class on him. He could land and spin and be heading off in another direction in the blink of an eye and cut corners and jump clean from impossible angles that no one else could attempt. He was unbeatable in his day in the Open Speed classes. This little 15.2hh Anglo Arabian … 
IMO they are truly the most UNDERrated influence on performance horse pedigrees out there …
