Vantaggi
As an MSP, you have an opportunity to touch a lot of different technologies, and learn those technologies. There are a lot of opportunities to work on technical projects. The older engineers are a vast source of knowledge, and this can be great if you are just started in IT.
Svantaggi
Unfortunately this is not a company I would recommend working for. Management culture is poor, with management more often than not pushing things off onto direct reports. Management doesn't want to deal with customer service issues, so pushes those off onto their subordinates too. General blame culture of scapegoating service desk engineers for issues, while protecting management and the business owner. The owner will act as though they care for their employees, but then has no issue scapegoating them to clients if something goes wrong. Definite churn and burn culture, with engineers worked to the bone, stressed and relied too heavily upon. There is no culture of knowledge-transfer, so engineers who try and take vacation are often paged or interrupted because the business has not set other engineers up for success. While there are some good people in this company, the management team is severely lacking, and shirks all responsibility to their reports, while paying people far below industry average for their roles. Managers are never interested in "managing" and providing a buffer for their employees in customer service issues. If that wasn't enough, the benefits are also paltry. If you work in a higher role that does project planning and implementation, forget being able to do those. The service desk is so disorganized, you'll spend all of your time dealing with service tickets, while management asks you why your projects haven't been completed. If you do get any real work done, be prepared for other team members to be unresponsive, unhelpful, and potentially lazy. There is of course no recourse for these employees, leading to faster burnout for real workers. Be prepared to work inside of an outdated system of ticket churning, where there is no automation or actual technology implemented around tickets, just a huge number of them.
