WINAvr или IAR?, для тех, кто работал в обеих средах. Опции

[Karl]

Программирую в WinAvr. Собираюсь попробовать написать новый проект на IAR. В связи с этим вопрос: стоит ли тратить время и силы на освоение IAR? Кто какие плюсы и минусы видит в той или иной среде?

Кто тут "С"шные библиотеки искал?
