A little fact. If your eidolon's element matches with your main weapon, it will get 10% stat boost. The difference between the base stats of both eidolon isn't that big, so 10% stat boost will make them equal, if you use a light weapon.
Apocalypse hat blind, but you should also consider:
1. it could miss.
2. boss' most deadly attacks are spells and ultis, which are not affected by blindness. If you count on missing normal attacks to survive, then your power is too low.
3. You can't summon/apply blind at the beginning, unless you have Apo as friend, so it is good for you friends, but less good for yourself.

On the other hand, Phoenix's summon skill (RST up) is useless in most cases. Later if you will face bosses with nasty debuff spells such as medusa and stronger ones, then this skill could save your butt, but blind won't... Medusa is for most people the hardest boss so far. With Phoenix's RST up and Sol's dispell, even ultimate level isn't challenging anymore.

I could unterstand, that someone would say, that apocalyse is superior than phoenix due to summon skills. If I have to choose them as Friend for common battles, I would like to use Apo rather than Phoenix too, but that's not your case.

Both Eidolons are equally strong imo. Apocalyse for general use. Phoenix for some specific, but really hard bosses.
Only considering the passive, if you are able to MLB the Phoenix, it will give 5% more light element attack than your 1*behemoth (40%-35%). 5% element attack up seems a little, but it will give you a signficant dmg boost in late-game, once you have huge attk boost through weapon skills.
A MLB Apo won't give you any passive dmg increase compared to Echidna (40%-40%).
The summon skill blind, well, whats the point, if you can't use it at the begin of the turn. By the way, Dark element has also tons of SR/R which can apply blindness anytime you want.
Of cource It's better to have them both MLB. If I were you, I would focus on Phoenix first and try to get 1 apocalyse at least.
Just to point out. Phoenix summon skill is entirely useless, there is no situation where it's useful. To put an example: I was using phoenix on Medusa ultimate, it didn't help at all. 4 out 5 party members were petrified. And when I went without Phoenix? 4 out 5 were petrified! So no difference, it just ups your resist a little bit. If you need to rely on it then you are doing it wrong. Even relying on dizzy is way, way better.
The only things that helped there were Amon with her debuff preventing skill and Behemoth with debuff removal. And of course dizzy to make her not move at all.
