The verdict
If your team sells to named accounts and wants a daily list of who is showing interest, I'd pick Albacross. It is the simpler tool and it can replace a separate outreach tool for a small team.
If you spend real money on paid channels, your sales cycle is long and finance wants to know which campaigns produced revenue, I'd pick Spectacle. That is where first-click and last-click reports mislead you most.
For a small B2B team with a modest ad budget, Albacross is the easier start. For a SaaS team with serious paid spend and a clean CRM, Spectacle earns its set-up effort.
