No, Bekele is not undoubtedly "THE distance GOAT". If you just list current World Records, I assume that athletes like Nurmi, Zatopek, Keino, Viren, Aouita and some more are not very high on your list of all-time greats. (is Kipchoge Keino some of your top 100? Just curious...)
Here are a few FACTS regarding Gebrselassie and Bekele:
1) Bekele came AFTER Gebrselassie (and therefore had to chase his times; we don't know at all if Gebrselassie could have run the times in the events Bekele's PB is superior). For example in Gebrselassie's 2nd 10000m WR 1997 in Oslo, he was virtually jogging the last lap, knowing he easily will break Hissou's WR.
2) Gebrselassie's combination of PBs over all the distances from 800m to Marathon is still better than Bekele's. (thats a fact, the slightly better PBs from Bekele over 5000m and 10000m (and also the big advantage over 2000m) can't outweigh Gebrselassie's advantage over 1500m, 1 Mile,, 3000m, 2 Miles, 10k, 15k, 20k, Half-Marathon, Hour and Marathon.) It might change in the future, but at the moment Gebrselassie's PBs are better (the combination of them) than Bekele's.
3) Span between global track titles:
Gebrselassie: 7 years, Bekele: 6 years
4) Span between global titles:
Gebrselassie 9 1/2 years, Bekele: 6 years
5) number of global outdoor meeting with medals:
Gebrselassie: 8, Bekele: 6
6) number of World Records: (Geb/Bekele)
2000m(i) (1/1); 3000m(i) (2/0); 2 Miles (2/0); 2 Miles(i) (1/1); 5000m (4/1); 5000m(i) (3/1); 10000m (3/2); 10k (1/0); 15k(1/0); 10M (1/0); Half-Marathon (1/0); Hour (1/0); Marathon (2/0)
7) Win/loss record: Gebrselassie>Bekele
8) Global titles from:
Gebrselassie: 1500m(i) to Half-Marathon
Bekele: 3000m(i) to XC long course
9) number of seasons with world class results:
Gebrselassie: 20 (depends little bit on the point of view)
Bekele: 13
10) span between global title and or world record:
Gebrselassie: 15 1/2 years, Bekele: 7 1/2 years
(add 1 year for both if you want to include junior competitions)
So, these are just a few facts which should be taken into consideration. But I still don't say Gebrselassie is the GOAT. For sure Bekele also has big arguments for this "title" on his side. Mainly (to me) his unique success at XC and his doubles at global outdoor championships. After his wonderful Marathon debut in a virtually solo effort it's a close decision I would say. For me, Gebrselassie is still the Nr. 1, but I can see why some people would opt for Bekele.
Just a note to the XC case: first, we should not forget that Gebrselassie also has had very good results here: 3.,4., 5. at the World Champs, victories over Paul Tergat. And also that Gebrselassie didn't had the chance to run a short XC like Bekele has had. Not a very proud assumption that Gebrselassie would have exceled here better than over the long course, with his slightly better PBs than Bekele over the shorter distances. I'm also always wondering why people always put so much evidence in the number of Bekele's doubles, but not in the number of Gebrselassie's records. In 2002, Bekele has proved that he is able to run two XC races of the highest quality on successive days. Fantastic, no doubt. On the next four occasions he has just proved his constancy in this department, but not some new qualities. Still great, I don't want to reduce this. But why not appreciate Gebrselassie's constancy over 20 (!!!) years?
