These are two very different things/endeavors. For one, when you create lessons for the internet, you have to think about how to appeal to a group of people, considering the size of that group and whether it’s worth it to create a lesson targeting them. Teaching this way is also much more of a one-way street. You present the lesson, from beginning to end. You do get feedback, either with words (comments/emails) or with metrics (views, purchases, etc).
When you teach a private lesson, you a) interact in real time and b) get to tailor each lesson to the student’s unique needs, regardless of how niche they are.
It is far easier to start teaching some private lessons, either in-person or online, as you don’t have to:
• Create a website for online lessons to live on
• Write, film, edit, and upload the lessons with good quality
• Work as hard to make your lessons stand out amongst a sea of online content.
When you start teaching one-on-one, you can probably gain a good 3-5 students just from church, friends, word-of-mouth, etc., especially if you teach multiple instruments. Consider the following:
• People value being able to take lessons in person, so your competition shrinks.
• People will be more inclined/comfortable taking lessons from you if they know you.
• You can make more money per student. You can probably obtain 5 students paying $15 for weekly lessons easily enough, making you ≈$300 per month. Making $300 per month through subscriptions, for instance, on a brand new (& untrusted) lesson site? It’ll take you longer to get that ball rolling, and you also have to think about your niche, shoot videos well, learn how to build a website, most likely pay for website hosting, etc.
That being said, the drawback to the local/friends/church side of teaching is that your students can end up being little kids or very casual musicians who may or may not be all that interested in actually learning 
BTW, I do think Guitar Pro is a superior software to TablEdit nowadays, but look into both of them and determine which is right for you.
