Best is subjective for any gizmo, what works for one business is a trainwreck for another, giving info on audience,budget and feature requirements is what you want to be asking to find something tailored for the use case.
Forewarning:
Best newsletter popup, is no popup these are reactionay items that can indicate a deeper issue. Always weigh carefully before adding noise to a stores experience. Typical side effects are sluggish page load, styling|javascript conflicts, and increased bounce rate. For reference check the feedback forums case after case of non-success with multiple widgets not being the magic button apps makes them out to be.
+10 years ago it was alert boxes, 5+ years ago it was window-popups, now it's modal-popups, adblockers,google and browsers will catch up. If modal-popups didn't exist how would you collect email? How would you want to be solicited for your email address?

http://optinmonster.com/pricing/ has a\b testing built in $9/mth
After such considerations try to test these apps|services at low traffic hours,preferably a/b test them , and|or using a duplicated-theme and the preview option(if able).
Never set-it and forget-it and be sure to disable unused apps that add to the client-side.
Though no matter how personally annoying, time and time and time again they are be shown to be effective at collecting email addresses, there is no guarantee those are good emails. When you add one of these gimmicks traffic must be carefully monitored for unwanted shifts and tuning to your specific audience. And conversions through the newsletter itself must be weighed ,as their's no point of hundreds of anonymous emails(adfdf@gurellia.com or similar) , nor immediate unsubscribes that don't convert.
Be sure to visit the site with an empty browser cache like a new user would have(incognito windows, different computer,etc) so you are not caught unwares of unwanted behavior.
We have it set up for exit intent, so I think when people see we are offering a 10% discount if they sign
This is a good example of one stores success, so don't feel frustrated if the same tactic doesn't work for your case. Install test and tune. Note also the uncertainty about what the results actually mean this is where the danger lies and can mislead you if testing is not carried out with discipline.
tldr; Always validate business assumptions, be rock solid in knowing your audience before using popups and prove usage with data.
