100 hours is more than nothing, and a type rating is better than none.
Ryanair will accept 100 hours and 737 NG rated pilots without you needing to pay for another rating - straight in if you pass the interview / sim check etc etc.
Easy have dropped their requirements to 500 hours so you are getting close with 100 hours - a hell of a lot closer than none.
Airlines basically have 2 questions. Are you employable (attitude, personality etc)? Can you pass a type rating?. Well you've answered one with the above. If you are not 'employable' then it doesn't matter how many qualifications you have in any walk of life, you will struggle to get a job.
Remember with the Stapleford gig you can also walk away and look for jobs before the type rating, saving alot of money compared with OAT.
Bottom line, is the same advice as is always given, go and visit both, see what you think, make your own mind up. Both places have good kit, both places have professional instructors, Both have an excellent record with graduates getting jobs with airlines. Both give the same qualification (ignoring the rating for the time being) one costs twice as much as the other.
