Lavos utilizes his vast array of alchemical knowledge to combine elements for varying effects and enhancements. Lavos is the quintessential alchemist warframe. As you would expect given this theme, Lavos requires knowledge of elements and their unique effects to be played effectively. Additionally, his abilities have cooldowns rather than energy. This is system that is wholly unique to him, and takes a lot of getting used to. These two factors, alongside his secondary ability inputs for elemental combos, make him a very complex warframe to play. Lavos is definitely a good warframe when played correctly, and the allure of his theme and visual design is undeniable. He imbues you with powerful buffs for any occasion, and his abilities are very effective for dealing damage when the correct elements are used. However, his complexity and cooldowns make him very hard to recommend to a new player. If you want to play as the alchemist of the warframe universe, you can totally pursue him and i'm sure you'll love playing him, but if the allure of playing an alchemist doesnt apply to you, I would reccomend pursuing another warframe.
