If you are looking to have a social or relaxing trek, those options exist. I've heard ABC is great for that. If you are looking for a challenge, or just an exceptional hiker, maybe EBC is right for you.
Should you book with Nepal Hiking Team
1000% yes. Whatever hike you do, it's a yes. Try to get Ram as your lead guide - he's amazing and made the whole experience. My assistant guides Bikas and Sabin were awesome too. Pretty sure everyone on their team is great though!
Little anecdote, we had a 12 yo along for our trek who got sick after one of our most challenging days. Ram, Bikas, and one of our porters carried her back down the whole days hike for emergency care and stayed overnight with her until she was in a helicopter on the way to Kathmandu's hospital with her parents. And Ram managed to catch up with us the next day. These guys are beasts! This can be a dangerous trek and Ram is someone that, after spending 2 weeks with, I 100% trust with my life.
Things to note:
Expect variable costs beyond the initial booking price. We needed a helicopter to reach Lukla due to weather conditions (to avoid delaying the trip). Budget approximately $1,000 USD extra for unexpected expenses. This stuff happens, it's part of the adventure, and it's totally worth it.
The coordination required for this trek is immense, and Nepal Hiking Team makes it look effortless. They have everything dialed in perfectly, but set realistic expectations about the challenges involved.
Be honest with yourself about your fitness and altitude tolerance. Remember that half our group needed helicopter evacuation - this isn't just a walk in the mountains!
