How do you choose the right online spoken English course in 2026?

I've been trying to improve my spoken English for a while, and I've realized that there are far more online learning options available now than there were a few years ago. The problem is that every platform claims to be the best, so it's difficult to know which one actually delivers good results.
My goal isn't to get a certificate. I simply want to speak English more confidently in daily conversations, office meetings, interviews, and while talking to clients. I can understand English reasonably well, but I often struggle to respond quickly or express my thoughts naturally.
While searching online, I found platforms like EngVarta, Cambly, Preply, italki, British Council, Lingoda, and a few AI-based speaking apps. They all seem to follow different learning methods. Some focus on one-on-one practice, some connect learners with tutors from different countries, some offer group classes, while others rely mainly on AI conversations and pronunciation feedback.
I also came across this comparison guide that reviews several online spoken English classes and explains their teaching methods, pricing, advantages, and who each platform may be suitable for:

It gave me a broad overview, but I know that real user experiences are often more useful than marketing pages or comparison articles.
For those who have actually taken an online spoken English course, what mattered the most in your improvement? Was it the teacher, the number of speaking sessions, regular practice, feedback, or simply staying consistent?
I'm also curious whether one-on-one conversation-based learning is generally more effective than group classes. If you've tried multiple platforms, what differences did you notice? Were there any features that looked impressive before joining but didn't make much difference in the long run?
Finally, how long did it take before you started feeling more confident while speaking English in real-life situations? Did you practice every day, or were a few sessions each week enough?
I'd really appreciate honest experiences—both positive and negative. I'm hoping your suggestions will help me choose a course based on actual results instead of advertisements or promotional claims.
