A verified complaint is "better" because if forces the defense to provide a verified response, but an unverified complaint is "better" because you don't have to be so sure about your allegations and you don't have to worry about making damaging admissions. If you're acting pro per and asking this type of questoin on a free public site, I doubt you're sure about anything in this process.
Employment litigators generally work on a contingency basis, meaning the plaintiff pays no legal fees unless and until they win their case. So filing an ADA case pro per signals to the defense, if the complaint itself doesn't, that the case has no merit because there's no lawyer.
See an employment litigator for help. There are many lawyers that specialize in these claims and know what they're doing.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
The common practice is to NOT verify the complaint, unless a specific statute requires that the complaint be verified. The reason is because a verified complaint can be used against the plaintiff, just like any other declaration, as binding evidence in the case. Essentially, the plaintiff is locked in to each and every statement contained in the verified complaint.
On the other hand, the advantage (strategically) of verifying a complaint in some lawsuits, however, is that it forces the defendant to file a verified answer (which can be used as evidence).
