are consultants just way more pleasant than bankers?

Based on the most helpful WSO content, your observations about consultants being more pleasant and having a better lifestyle compared to bankers are echoed by many. Consulting does tend to foster a more collaborative and people-oriented culture. Consultants often highlight the following lifestyle advantages:

1. Work-Life Balance: While consulting hours can still be intense (70+ hours during busy projects), many consultants report having weekends off more consistently compared to banking. Your friend's experience of not working weekends aligns with this trend.

2. Collegial Environment: Consulting firms, especially MBB, emphasize team dynamics and culture. Many consultants genuinely enjoy spending time with their colleagues outside of work, and firms often prioritize hiring people who fit well culturally.

3. Diverse Backgrounds: Consultants often come from a variety of academic and professional backgrounds, which can make for a more interesting and dynamic workplace. This diversity also extends to hobbies and interests, as you've noted.

4. Broader Skillset: Consulting work often involves strategic problem-solving, client interaction, and varied projects, which can feel more engaging than repetitive tasks like comps and model refreshes in banking.

5. Personal Connections: It's not uncommon for consultants to form close friendships or even romantic relationships within their firms, given the collaborative nature of the work and frequent travel together.

That said, the trade-offs include lower pay compared to banking, especially at the junior levels, and the potential for grueling travel schedules. If lifestyle and culture are your priorities, consulting could indeed be a significant upgrade for you.
